Re: Increased compile resource performance[excluding draftCompile] with single perm
Will you be giving the -XX:+UseCompressedOops option a try when on the 64-bit JVM? I'd be interested to hear about your experiences. Good luck. C.

Re: Increased compile resource performance[excluding draftCompile] with single perm
Hi, Thanks for all the responses. The build tips surely helps Lukas. Yeah the whole 2m stack space issue may have been resolved but to be perfectly honest I don't feel safe yet. I have found that I will have to resort to upgrading to a 64bit os and or JVM. I dont really need the EC2 as I have a very decent build server that can handle the load. Its just a shlep(and slow) to commit to our source control and get from the server etc.. etc.. I'll post my experience once I have upgraded to 64 bit. Thanks again for the responses.

Re: Increased compile resource performance[excluding draftCompile] with single perm
Yikes, that's a lot of memory! I missed the note regarding "x86" in the OP, so that puts you on a 32bit JVM. Have you thought about renting a High Memory EC2 instance over at AWS for a couple of hours? C.

Re: Increased compile resource performance[excluding draftCompile] with single perm
SOYC option on large project takes immense amount of memory and hdd space. However, runAsync splitting is compiled properly without - draftCompile switch. I have ended with -Xmx32768m java memory for GWT Compiler using -soyc command line switch (i guess 8GB+ is sufficient). The generated files took over 2GB space on the hdd, and it took over 40 minutes to finish. There are 130 split points. Normal, production build takes less than 2 minutes per iteration. Hope this helps.

Re: Increased compile resource performance[excluding draftCompile] with single perm
Are you sure that you need the 2mb stack? I seem to recall there was a problem a while back with stack overflows resulting in some people suggesting large stacks. I think that's been fixed now. Are you using a 32 or 64 bit JVM? What are the exact compiler and JVM arguments you are using? Cheers, C.
