Look more closely; The green line is linux-2.6.21 with the new glibc. I sent my kernel config to some linux hackers to look at. We removed some minor debugging code to get these results. I have also tested with 2.6.22 with no real change. Although many other people saw great improvements. I will update to fedora core 7 eventually although I supposedly have the relevant fixes. In my mind I hope that linux addresses their issues and that really isn't my primary concern. My primary concern is that freebsd is now becoming competitive on higher-end server class hardware for a variety of workloads where it was not before. I benchmarked linux just to see where we are at as they are generally considered fast and scalable. The credit for the great improvements we've seen from 6 to 7 should go to the many developers who have put a lot of hard work into locking individual subsystems and the primitives. The scheduler is only able to do better now because there is less contention over all.
