I know without deep details this may be hard to answer but looking for some general thoughts.
We have 4 front end web servers all on Coldfusion 7. Java 1.4.1.13. Dell Xeon 4 gigs of Ram, dual quad core Nothing by CF runs on these boxes. All the code lives on NAS on a gigabyte network. Throughout the day when looking at seefusion we will see short windows of time, maybe min or 2 where pages that normally load pretty quick with take 30 seconds for example to execute the TTFB. Queries are in ms range but the page just seems to stick. For some testing I moved all the source code to the local Drive on 1 web server. I do notice less pages hanging but still see little blips. What I see as a big difference is when my app first loads on the NAS it takes up to 100 seconds, locally 10 seconds or less to load in all the objects. Performance overall on the local machine seems faster. Roght now the code on the local machine sits on C drive as well so I suspect if I added some more drives it would perform a little better with having to compete with the OS. For caching I have both Trusted cache and Save Class files checked and max number of cached templates at 2000. Max is connections is at 24, I know I could go much higher but this seems to work best. I would assume overall that the site running locally will perform faster than over a gig switch. Maybe fiber would compete here, not sure. Im trying to figure out why the sporadic high TTFB comes up. Are there any other settings, places to look, IIS settings maybe, to try and see why this is happening... or is it simply a burst in traffic that causes some concurrency issues? Thanks in advance.
