I put history and spool on seperate busses(I'm poor, I can't afford 15 SCSI controllers :) > There's only 5 drives on it. I'm interested in figuring out > what's wrong with the layout.

I fiddled with the setting a little, and found 1k appeared to give the best performance. If I remember correctly, you want the "average" article to fit in one interleave. I may be way off on that though. With the interleave set to 1k, we're able to keep up with a releatively full feed (we don't get de.* and a couple non-english hierarchies). We've got SCSI time to burn it appears. No problem receiving the feed. Note, however, that we don't have many active feeds out(ok, only 1 "full" feed), and we have a relatively low reader count(we max out at about 45). On the other hand, we don't anywhere NEAR enough drive space(5G now, adding 4 next week). But overall, I don't have any problems. Our response time is good, and the system's not hiccupped in about 6 months. BTW: We're running 2.1.6 now. I don't think 2.1.6 does noatime though(maybe I'm just being dense here?) > to have a looksee at the archives of -hackers.
