- Our configuration is much like yours, Dave. We found the greatest
- improvement was to be had by going to a faaaaast SCSI drive. The ESDI drive
- was NOT an improvement.
-
- Another thing that lead to some improvement, but not much, was to "nice" the
- news unbatching process. The hard drives still grind, and I/O is still the
- major bottleneck on the system, but the users can get in there while the
- unbatching is happening, and nobody complains about slowness.
-
- A typical Unix performance problem caused by placing active partitions at
- opposite (or at least near-opposite) sides of a disk. That kind of
- configuration causes a lot of unecessary overhead as the disk heads spend
- all their time seeking and less time actually doing reads/writes. Of
- course, the news is so large that it will cover most of the disk anyway!
