Do you have indexing turned off on all your drives? How many processes are running in your Task Manger when you are doing this? Have you tested the performance of your drives with something like CrystalDiskMark?
Thanks for the reply and the questions.
No, indexing is on, however it shows "complete", and only a few folders are being indexed (all on C:). The ‘Pause’ button is disabled, which indicates to me it is not active at present.
Processes? Yikes; more than I want to count (40-50?). Though most of them are at 0% and don't seem to be doing anything. I closed my browser (which has a lot of open tabs) and tried again. CPU usage peaked at < 20% this time, but the clip still doesn’t seem to play noticeably faster.
I hadn't done any disk performance testing, but I just downloaded CrystalDiskMark and tested the drive playing the clip. Sequential read speed is 502 MB/s. There's also a Seq Q32T1 (don't know what that is) at 551, and 4K Q32T1 at 502. Only 4K read is slow at 20 MB/s, but obviously the clip isn't being read in 4K chunks (I hope!).
Looks like this mystery is going to go unanswered. However, if I do ever find out, I will try to remember to update this thread for the benefit of anyone else having the same question.
Thanks again, Bill.
I turned off indexing (disabled the service) and tried again, but it doesn't seem to make a noticeable difference. There probably wasn't any (or much) writing going on to the drive (C:) that had folders indexed while I'm playing the clip from another drive, as I had very few things being indexed.
Ah, I don't have to count the processes! Mine shows 60 processes (though a bit over 1000 threads).
