I would remove the cachedwithin or throw more memory into the machine. For a high traffic site with 500 users, this will chew through memory very fast and can be a performance boost, but not if you don't have enough memory to do so.

A prayer in a public school!

RAM used by Coldfusion MX 6.1 rises to 700-800 Mb during the rush-hour. There is a MAX set to 1024 Mb. The problem is when the memory usage reaches approximately 500 Mb Coldfusion slows down greatly for a few secons every minute, what can be seen in the traffic meter: http://www.draugas.lt/jvm/memory.gif When Coldfusion is restarted, everything works fine until the memory usage gets to >500 Mb. The interesting fact is that when the number of visitors drops down greatly, the memory usage decreases very slowly and these Coldfusion lags remain. "cachedwithin="#createtimespan(0,0,5,0)#"" is used a lot in the website. I guess JVM doesn't clear the query cache. Maybe anyone can help to solve the problem? Maybe there are JVM commands which help to clear the query cache faster?
