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.

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.
