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.
still any idea why MAXBSIZE is 128kB by default. for modern hard disk it
is a disaster. 2 or even 4 megabyte is OK.

actually IMHO much more tweaking is needed with linux, at least from what
i know from other people. And they are not newbies
