performance issues

Mar 23, 2012 5:15 PM

I just downloaded and installed 64-bit CF10 Windows (coldfusion10_p1_win64_021712) in server mode in conjunction with 64-bit Apache 2.2. After install, everything seems to work, but performance is very slow (10-15 seconds per page load time in CFAdmin). I have CF9 installed also.

    Check you don't have server monitoring/profiling running. I had a similar problem. 


    Kind regards,

    No, I can tell you that I explored that myself a couple of weeks ago, and added found and added the libraries necessary to make that go away. When I did, it made no difference in startup time or runtime for requests.


    As for your problem, I would propose to counter Liam, who suggests (reasonably) that perhaps server monitoring could be getting in the way (the CF Admin Server Monitor, available only in Enterprise and Developer editions). While he suggests “monitoring” and “profiling” could be at issue, I would contend instead that “memory tracking” (the 3rd of the 3 buttons at the top) might instead be the issue. That frequently causes problems (for some, though not all), while “profiling” is less burdensome, and “monitoring” far less.


    In fact, the beauty of having “start monitoring” enabled is that you can see what requests are running, how long, and you can get a “stack trace” to see what exactly is making a request take a long time. I’ve written more about the monitor (in a 4-part series of articles, starting here: and about stack tracing ( dumps), including presentations on both



    One other thing: if you go back to starting CF normally, rather than at the console, there will be the same log entries and more in the Re: performance issues\cfusion\logs\start.log. Look there to see if there’s any explanation, such as outofmemory errors that may explain your slowness.  There’s nothing that makes CF10 inherently slow, so there must be some explanation. You mentioned slowness in the CF Admin. What about in apps other than the admin? Also, what if you enabled the built-in web server and accessed CF using that, rather than via Apache? That may show a problem in the Apache/CF connector (not there should be one, but it may help you focus on the real source, if none of the above pans out).
