I haven't done a systematic study with gcj recently, but my impression is that it's a substantial win for multiprocessor servers, and a mild loss for uniprocessors. I believe it works reliably on at least X86 and IA64 Linux. I thought others had also used it on other platforms? (It doesn't work on Solaris, since it's incompatible with the thread-stopping code there. We would have to switch to using linux_threads.c there to make it work.) Hans
