Given a reasonable news server, I don't think that active update time is going to be the big concern, in any case.

I am doing it on my new pet box, newsfeeds.sol.net, and I have seen peaks of 44 articles per second (INN1.5, FreeBSD 2.2C, disks async, PPro200, 192MB RAM) compared to newspump.sol.net's record of 16 (INN1.4UNOFF4, FreeBSD 2.1.5R, disks sync, P133, 256MB RAM). But I am a little paranoid that a crash may not come right back. :-) File deletions are so quick, they blow my socks off. ;-) ... JG
