What Lyle outlined seems to be the case (at least for me). I went from 2gb to 6gb of RAM on my Windows 2008 64bit workstation today. The maximum that I have been able to set the Dev Studio is -Xmx1568m. If I add much more to that I get errors trying to start Dev Studio.
I have not been able to find a place within the Java settings to increase the max JVM heap. Is it a environment variable that I am missing? So here is a question. I have the 32 bit 1.6 JRE installed. Will that limit the heap size to a 32bit limit? When building 64bit 2008 machines one of the apps (the AR Suite installer maybe?) complained about the 64bit Java so I went to back to the 32bit. Is my setup an invalid test of expanding the max heap over 1.5gb? I am trying to do a full export of Help Desk/SLA 6 and a bunch of custom apps from a 7.5 p1 server using Dev Studio 5 p2 with the new Xmx1568m setting now. I have not been successful with previous full export attempts. I'll update the thread if it is successful.
