I have coded some simulator to study routing algorithms for my PhD thesis and I have tried running my tests with jdk1.3.1/FreeBSD and linux-jdk1.4.0/FreeBSD. It's damn slow... I mean far more than I expected. I used to do tests under jdk1.2/hotspot-server/win32 and jdk1.3.1/win32 and I thought freebsd was just a bit less performant. What a surprise. To give an idea : I think win32 goes more than 5 times faster than bsd. Note that this is not a complaint mail. I am willing to help as far as I can to make FreeBSD the best platform for java. I was just wondering if someone had some hints about some performance issues that might help to still use FreeBSD for my tests. I mean before the day we have full powered hotspot/FreeBSD ;) I ask this because it is quite annoying to have to code/debug in FreeBSD (because even with vim, windows sucks for dev) and run in windows. At least I illustrate the "write once, run anywhere" ;) It becomes for the occasion : "write where you like to, run where you need to". Maybe the linux-ibm ? or even Kaffe ? What can be done with JIT like openJIT ? I know I should test on my own but you all know what it is : the deadline for the article was... well, I think I should go back to paper quick :( Herv=E9 PS : I tried building the native jdk13 with -O9 (!) and I can't notice any improvement.
