Hi all,

Just a quick question.
Is there any way to reduce the startup time of J3?

Thanks,

Hi Chanwit,

Yes, by using the vmkit command line tool instead of j3 and passing llvm options:
./Release/bin/vmkit -regalloc=fast -java MyApp

Additionally, if you are not using MMTk, you can precompile the base classes (eg java.lang.String) by following the instructions at this page:
