For what it's worth, cvsup2.freebsd.org is set up with two mirror pairs, one for / and friends and one for all the cvs data (/cvs). The one thing I added that made a HUGE difference was ram for the hardware raid controller (it had 16MB to start). The filesystem "stuff" (inodes, etc) is all just the default for a partition of that size. It appears to have between 5 and 30 cvsupd's running at any given time (I should probably take 15 minutes and have it keep a record =), and I have never (though I would like to) tested the maximum number of connections it can handle gracefully. I have not noticed or heard any complaints about its performance. It's running only cvsupd (i.e. ftp2 is a different physical box). I'm not sure how well raid-0 will serve you, especially if you're going to do cvs/ftp and www together. ftp2.freebsd.org is the exact same configuration, except with a big raid-5 instead of two raid-1s (it runs stock ftpd and thttpd), traffic graphs are at http://ftp2.freebsd.org/etc/. I'd be interested to hear the configurations used by and experiences of the other mirror operators.
