First, let me say that the results I'm excited about are that JBoss and Jetty start up without dumping core, and that I can't make Jetty fall over (well, not before my 5.0-CURRENT box panics in msleep() due to lock contention with vm_pageout_scan() on the process lock). I'm not saying it's fast, and I didn't expect it to be, because I have all the debugging knobs enabled in the kernel (witness and friends). However, I see that the native jdk-1.3.1_p8 VM w/ Hotspot and native threads handles my simple test case of instantiating 10,000 relatively simple objects from strings taken off stdin is 3 times faster than the -classic VM. Looking at the benchmarks on shudo.net [1], it seems like ShuJIT is _significantly_ inferior to Hotspot. But I'm really keen to start lurking now -- I know how annoying it is when clueless newcomers make a lot of noise on their first day. Ciao, Sheldon.
