Re: Benchmarks (who has the fastest free VM)

The resulting JikesRVM binary and image keep seg faulting however on my machine The most likely explanation for this is that your glibc is not using the GS register for pthread local state. You can kludge around this by building Jikes RVM with RVM_FOR_SINGLE_VIRTUAL_PROCESSOR=1. However, the

Hi all, Before going to the Libre Software Meeting and LinuxTag http://www.libresoftwaremeeting.org/ http://www.linuxtag.org/2003/en/index.html I wanted to know how the different free VMs were doing. So I did some micro benchmarks against them. I didn't have time to do more complete benchmarks

Re: Benchmarks (who has the fastest free VM)

Hi Mark, You can find performance measurements SableVM compared to other free/non-free JVMs running some real benchmarks (SPECjvm, Soot, SableCC) in my Ph.D. Thesis. Look for the Chapter on performance measurements. More precisely, you might be interested by Tables 9.1 and 9.2 on page 118.
