    PPBM4 Benchmark : Discussing my results...

    kohns Level 1

      http://ppbm4.com/Benchmark.html

       

      My stats are under kohns_01.

       

      Why come does it come that HB-i7core-975 , Solo7   Graham and my 'Export AVI (Sec.)' result is so poor.

      Any idea on how that comes (what is importand for exporting AVI) and how to improve it?

       

      It is a fresh install and I am still tweaking it.  I already:

      • removed/disabled a lot of services
      • disabled firewall
      • turned of disk indexing
      • changed windows to "Best Performance"
      • turned of Themes
      • ...

          Exporting AVI is a disk intensive benchmark.  Run HDtach (a free utility) on both your OS disk and your RAID array and report the burst transfer rate, the average read transfer rate and CPU utilization.

            Thanks for the feedback.

            My system crashed... and getting : unable to find NTLDR ... so I will do those tests after I recovered.

            Soon I hope ...

              Very observative that you noticed Graham's, Horatio's and your own AVI scores to be less than expected with your disk setups. You all have good disk setups, and one would expect better results. HDTach, as Bill mentioned, can be indicative of potential bottlenecks that keep you from top-notch performance. In addition it may be wise to inspect Process Explorer results to see what processes are running in the background that prevent better results. But first get your system up-and-running. Good luck.

                I am almost there... finished the reinstall of windows/windows-updates/drivers and took a new image.  I am now tweaking it again before I start installing Adobe and do those tests again...

                 

                It should be a little faster now because I now also replaced my 160GB WD 7200RPM with a 150GB WD Velociraptor 10000RPM.  Can't wait to run my first benchmark again...

                  Ok my PC is "ready" for the first test... but it is not looking much better even with the new faster OS disk ... on the contrary ...

                  And below is a list of how I configured services to start/disable/...

                  Next to that I also disabled indexing on all drives and defragment all drives seconds before I ran the benchmark

                    While waiting on your thoughts on my above results I wanted to do some more investigation myself  by comparing my disk setup and HDTach results with Harm his results.

                     

                    I found this picture from you Harm in my other thread and wanted to compare them with my results (see above) and think you made some typo errors ...

                    HarmSetup.JPG

                    First surprising thing is that your 2x1TB raid0 has a burst speed 4x higher then your 12x1TB raid30 !?!?

                    So I think those 2 numbers should be switched.

                    And if they are switched I also think that a burst speed of 1158 for your 2x1TB raid0 is impossible.

                    If I compare your numbers with my numbers we get this graphic:

                      Burst speed is quite dependant on how much cache the controller has, how much cache the disk drives have, the synthetic benchmark used to measure this data and the transfer rate of the controller to the system bus.  I do not put much faith in burst rate except if it is lower than "normal" it may mean a bottleneck in that specific system.

                          Exporting AVI is a disk intensive benchmark.  Run HDtach (a free utility) on both your OS disk and your RAID array and report the burst transfer rate, the average read transfer rate and CPU utilization.


                          So you are saying this is a disk issue.  So I am (in the first place) comparing the disk setups.
                          Not that I only want to focus on that off course... on the contrary if out of this topic we find other intersting tweaks that would be great of course.

                          So let me just for a couple of seconds think about burst speed and what you wrote above... in point 2. and 3.


                        2. My Raid controller ARC-1220 has 256MB Cache Memory and supports 8*SATA II.  I have inserted the controller into my x8 PCI-E slot (so using the max potential)

                          Harm his ARC-1680ix-12 controller has a default of 512MB Cache which is twice my amount of cache I agree.
                          His controller however also only supports PCI-E x8 so no speed gain on that.
                          So the only difference would be the double amount of cache.
                          But that is only for his 12 disc Raid30 volume.
                          This controller only support 12 disks internally so his 2x1TB raid0 must be configured (just like me) on the motherboards raid controller and we have the same motherboard, Asus P6T, so I can still not believe that he would have 1158 Burst speed on his 2x1TB RAID0 disks

                        3. This still does not explain why our Export AVI stats are so bad.
                          If you look at the charts on the http://ppbm4.com/Benchmark.html website there are people with much worse disk setups that have like 3 times better values for the Export AVI results.
                          I don't think my HDTach results are bad unless you consider Harm did not write a type error and his 2x1TB RAID0 disk burst speed is considered normal.

                         

                        Thanks for thinking with me

                          Sorry, but Harm has an ugraded Areca with 2 GB of cache.  With newer Areca's you can now even go to 4 GB

                           

                          I have a second Areca and it has currently 512 MB of RAM.  Shortly I will be upgrading to 2 GB and will report the differences.

                            That could be but still that would only explain the HDTach results for his 12x1TB Raid30 volume... not for his 2x1TB in raid0.

                             

                            And that still does not explain why myself and some others have so bad numbers for AVI Export since other users (in the spreadsheet) have 'worse' disk setups and 3 times better AVI Export results... which was the main reason I opened this topic.

                             

                            And off course Harm is 'leader' in this... it is not my intention to measure myself with him... I only put his stats against mine to see if there was a problem with my disks HDTach results.

                              You are both correct and wrong.

                               

                              Correct in that the raid0 burst results are strange, they appear too high, but that is what HDTach reported.

                              Wrong in exchanging the burst-rates for my raid0 and my raid30. There was no mix-up and yes, I was as surprised as you that the burst rate was that low on my raid30, but that is what HDTach gave me as results. On a side note, you will be hard pressed to find consistent and comparable test results when you ruin these tests a number of times. There will be meaningful differences between tests. So the message is, do not stare at the results too much but consider them as indicative of your systems performance.

                               

                              Your average read speed with 6 x raid0 is about the maximum achievable (6 x 115 = 690 MB/s)  with nearly empty disks and negligent overhead. That is a fantastic score.

                               

                              BTW: I had a disk crash on my notebook, which took my attention with reformatting/reinstalling/etc. and that is why I did not respond to your other post. I hope you can understand...

                                Like I wrote earlier there are other persons in the benchmark chart that have worse disk setups than mine.  And you just confirmed there is nothing wrong with my disk setup and performance.

                                So that being out of the way... which other directions can we go from here to see where the bottleneck for these poor AVI Export ratings lies?

                                As I wrote before:

                                - This is a fresh install

                                - All disks are as good as empty and defragmented just before I run the benchmark

                                - A lot of Windows services are disabled and stopped (see lists above)

                                - No virusscanner installed and the firewall is turned off during the test

                                - ...

                                 

                                BTW: don't worry ... I don't mind you only were able to reply today... I am not expecting any reply withing the hour ;-) . To be honest I find the response times on this forum very correct. And I appreciate your and others help very much...

                                  Welcome to the world of sometimes weird and sometimes wonderful results.  While Harm was fighting his notebook disk problems I had a memory module and a fan fail in my Internet computer while I am experimenting bringing up a third computer (a new --for me i7-920).  In the meantime I am trying to find out why I cannot repeat my data and now I am getting slightly slower results from PPBM4 with 4.2 Premiere than I did with 4.1 and in addition fighting eccentric behavior with conditional formatting in Excel and saving to the data to html (for the results page).

                                   

                                  One thing that is missing from the PPBM4 information is just exactly how some of these people are getting their RAID--i.e. what controller are they using.

                                   

                                  Just to show you how things can change here is a test I ran with 'Windows 7 RC and two different nVidia driver versions.

                                    That is strange Bill... what has a graphic driver to do with disk performance...

                                    I don't think the graphic driver had any influence... I am more thinking about:

                                    • the big time laps between you taking these 2 stats (more then a day between)
                                    • how much did the content of your disk change: a lot of data changes occured, fragmentation , ...
                                    • what other services ran during that time (there might be a big difference)
                                    • did you take the test right after booting up or did you work for a while
                                    • ... etc....

                                     

                                    And if we look at your stats that is a difference of roughly 15% but which could be explained by above points.

                                    That would still not explain why my AVI stats are > 300% slower than comparable or less performant setups.

                                     

                                    You are right type and setup of the controller will play a big deal... but also how you formatted your disks ( NTFS cluster size etc. )

                                    So you might want to add that to your chart to have better comparisons.

                                      Well those video driver tests were done in the same setting.  Absolutely the only thing that changed was the drivers.  This was done when some rumors were circulated about new graphics drivers "hogging" the PCIe bus.

                                       

                                      Edit: I just took a look at the date and time on HDtach.  They were done on sucessive dates (July 1st and 2nd 2009) but since they were done on my editing computer it is only turned on when editing or benchmarking.  If I remember correctly this was done with the Quadro FX1700 and before Areca had a Win 7 driver.  That accounts for the higher than currently posted AVI encoding times.  But it does show that the slower array performance does cause a slower encoding time.

                                       

                                      P.S. When benchmarking I defragment generally at least daily if not more often

                                        That does indeed make sense :  the graphic card is sitting on the same pci-e bus as your raid controllers is.

                                         

                                        But that would still not explain why my AVI stats are > 200%-300% slower than comparable or less performant hardware setups:

                                            * You wrote AVI is mainly disk speed.

                                            * Disk speed could be influenced by the graphic driver so that would/could explain 10-15% difference but ot all the rest.

                                         

                                        Let us take for example Ozzi (Ann).  She hits a score of 2.8 for AVI compared to my 4.5 with a lesser CPU and only 2 disks in Raid0.

                                        I am pretty sure my disks are 2-3 times faster than hers. So where does that difference come from...

                                         

                                        Is there anything I can tune further (running services, other windows tweaks, ... )

                                          Sorry I slipped to a wrong line when I looked at your graphics card but try going back to an earlier driver.
