How much memory can I set to virgo use? We are using eclipse virgo 3.0.2 in production environment with sucess. But we using only 1g of ram because we don't know if eclipse virgo supports much more memory. We're moving for 3.6.0 version.

You can change Virgo's JVM memory by editing the files (a least at 3.6.0.RELEASE):
\bin.dmk.bat (windows)
changing the java_opts parameter:
JAVA_OPTS="$JAVA_OPTS -Xmx512m -XX:MaxPermSize=512m"

If you run 32bit os, maximum heap size is about ~ 3/3.5 GB.
In 64bit systems (with 64bit java of course) limit is in terabytes,i quess.
Remember not to set the heap too high, only slightly higher than your application requires. In case of bigger heaps remember also to set the proper gc algorithm.
