Hello, I've ran some tests just this past week (in fact I emailed freebsd-general about this yesterday), unfortunately however it was comparing performance between 5.0.51 and 5.1.26. http://paul.procacci.me/benchmarks/freebsd7-Release.html 5.1 performs worse than 5.0 at higher workloads. I'm unsure about 4, but am quite sure moving to 5.0 is probably the best decision you could make. ~Paul
