I would say the most common is 512 allocated as this is the default but doesn't mean it is right for your application.
If you have an -xms setting in your jvm config then this will also mean that the jvm will take all the memory allocated at start up. Really, it's a tuning process - load test the app, review the GC, Mem stats and jrun threads and then adjust your JVM (and Jrun Threads) accordingly.

This morning, RAM usage is running at 400 meg or so, of an allocated 512... with spikes of nearly 500 meg. Just wondering what is common... >>> [EMAIL PROTECTED] 29/03/2006 9:52 am >>> Hi Scott, This is all down to how your application handles it memory. If you allocate the full amount possible (approx 1GB) then you may have long garbage collection cycles - too little and you can get out of memory issues. Dual processor machines will handle GC much better so you can afford to up the JMV memory the more processors you have. I would not like to run a windows server with less than 2GB total RAM on the server so that you have the flexibility to go to the full 1GB JVM memory if required.

How much do you allocate to coldfusion (I think I mean allocated to jrun?) ? I assume the machine has nothing on it except for coldfusion and an OS like windows 2003.
