This particular box has only ever has 2.4.1 on it. Initially it was a 
feeder+reader with tradspool. Pretty soon expireover and expire times 
started going downhill so I changed to timecaf which seemed to help.

I then moved reading to another box (linux on a P2 400) which didn't 
suffer the same long expireover and expire times. The Ultra 10 became 
feeder-only (no overview) using CNFS and performance was good (with 
expires taking about a minute).

I then moved feeding to a new P4 with 1GB RAM and U320 SCSI disks 
(which rocks) and changed the Ultra 10 to a reader using timehash 
(because timehash had worked well on the linux box). This is when 
expireover times really started increasing, especially when I started 
carrying a full text-only feed (about 41,000 groups).

Thanks for looking into this - I'm sure expireover will still be 
running first thing tomorrow so I'll try and get a more interesting 
trace.

Thanks,

Mike.
