We're using the ccd for striping news right now and it's really quite
fun. Our server is a P133 with two adaptec 2940UW's, and a few 4gb
drives (soon to be replaced with 2gb drives).

Yes, and yes.

DEFINITELY yes. The sharedactive patch is a huge blessing for your
RAM consumption. It freed up almost 25 megs on our server when we
installed it.

We're very pleased with it. We made a few mistakes with it (using
slightly lower quality drives than we should have and using 4gb drives
instead of 2gb drives) that we're correcting now, and the performance
keeps going up as we do. Using ccd was a good performance boost as well;
probably not as much as an external RAID array, but it also didn't cost
us an arm and a leg.
Joe Greco would be a good person to ask about a FreeBSD news server -
he runs a fairly large one and has been very successful doing so under
FreeBSD.
