"Common usage" is vague. While FreeBSD might do ok for some applications (dev box, simple workstation/laptop, etc), there are other areas that require additional tuning to get better perf that arguably shouldn't as much (or there should be templates for doing so): 10GbE and mbuf and network tuning; file server and file descriptor, network tuning, etc; low latency desktop and scheduler tweaking; etc. Not to say that freebsd is entirely at fault, but because it's more of a commodity OS that Linux, more tweaking is required...
