To compare the kernels, I suggest linking both benchmarks -static, and you'll find that FreeBSD's fork/exec performance is a little slower than Linux's (not an order of magnitude :-)). I have been working the issue, and think that I have a few more efficiency improvements in my bag of tricks (running on my own -current tree.) I'll probably commit some of them before the next snap.
