In fact I wouldn't be surprised to hear that you have the best figures worldwide for your workload! I know it's an old machine and the ~125 specint aren't particularly impressive nowadays, but you are only using about 3.5 days of CPU time a month and a faster processor wouldn't help. You can always upgrade the processor card when this becomes a problem. With all the SJU lists moved to the box I would increase storage from 64M to 128M. I would also consider buying one of these $2-3k RAID controller with battery backed up writeback cache and reconfiguring the disks as a RAID 0+1 array for the spool and a RAID 5 for the rest, to improve both performance and reliability. You have room for 7 disks in the box, ie you can add 3 before you have to start replacing the old 1G drives. >Data base searching is a critical factor in the Information Center I am >developing on the WWW.
