I have a CF 8 server that seems to be randomly running slow all of a sudden. As far as I can tell, doesn't seem to be any application code causing it. Doesn't seem to be any abnormal DB activity and I tried running some simple HTM pages and those get returned fast. I only get slowness on .cfm pages, even if they have no DB queries or processor intensive operations. As in, I have a .cfm page with "This is a test" written in it and it's slow, as opposed to the .htm file with the same content. So it doesn't seem to be DB or web server related, which has me down to thinking there's something funny happening with the CF server itself.
For background, this is running on Windows Server 2003 on IIS. The web server is dedicated, so there's no DB server or other such process running on it. One thing I noticed, but that may be completely irrelevant, is that w3wp.exe is using 150MB of RAM and is spiking the CPU a bit more than on another server that I have setup exactly the same way, where the same process uses only 50MB of RAM.
Any ideas on what could cause this type of slowness? I tried looking into JVM issues, but it's kind of difficult to know what to look for as far as thread dumps are concerned. Any help is appreciated.
