Yes; Marcel and I fixed those problems with the Linux abi support a few months ago in FreeBSD-current and merged the changes back to -stable last month in time for the FreeBSD 4.3 release cycle: > "native threads" seem to be emulated by processes, > ps -axu > shows on java process per thread when running threaded stuff (like Volano > benchmark, > which by the way doesn't show similar huge increase in speed). > Just FYI, native threads on linux _are_ processes; they're very heavyweight and not terribly scalable, given how the linux scheduler works. FWIW, you should also be able to run the IBM JDK 1.3, which I think is faster than the Sun version. I'm running an older version of this and it works fine here. Lastly, Compaq's Linux JDK works on FreeBSD/alpha.
