My personal thoughts on all of the complaints that FreeBSD isn't fast enough and the Phoronix benchmarks aren't representative of true FreeBSD performance. Disclaimer: I don't know if the Phoronix benchmarks do tuning out of the box or not on Linux, so if they do, please correct me Matthew. The u

IMHO, no offence, as always. As were told, Phoronix used "default" setup, not tuned. So? Is average user will tune it after setup? No, he'll get same defaults, and would expect same performance as in tests, and he probably get it. The problem of FreeBSD is not it's default settings, some kind of v
