Ron, It sounds like you had a disk I/O bottleneck behind a CPU bottleneck. Once you solved the CPU bottleneck you ran into the disk I/O one. There may yet be steps you can take to optimize the disk I/O environment. I hope that your comments about steps you have already taken include optimizing your IMAGE sets. If not, this can be a big place to gain some efficiency. I would encourage you to run a HOWMESSY report and take a look at those sets in the HEALTH database that you know are very busy (SERVICE?). Then repack or resize as needed.
