[cosmo-dev] Memory Usage

[Matt Robinson]

The cpu hits 99% when accessing a calendar via any method. Yes it does 
go 99% at the start but then goes to 0% as it should. Server is AMD 
64bit 3200+ with 4GB ram running Windows Server 2003 Enterprise 64bit. 
Decided on this as I could not allocate more than 1.6 GB ram to the Java 
VM on 32bit.

 JAVA_OPTS="-server -Xms3048m -Xmx3048m  -XX:NewSize=640m 
-XX:MaxNewSize=640m"

I know that I am probably giving it too much ram, but it will take all 
of it and then run 99% and hang there. If accessing through web client 
error is something like "could not load items". Thunderbird just sits 
there with nothing at all. There are 5 Calendars I am trying to load all 
of which span only half of 2007 and 2008.

Thanks,
Matt
