Another item, FWIW...

We have nightly batch processing. Since the factory is closed
for the summer period, I can compare runtime figures before and
after the upgrade. Just to pick one item, the CONVERT of the
indexed RMS files runs 10-15% faster. Same file, same number of
records, same BIO, DIO and pagefaults, just runs 10-15% faster.

One example, the bottom 4 are HP 8.2 and the top 2 are VSI 8.4-2L2:

Elapsed Time:  0 00:00:01.85  CPU Time:   0 00:00:01.54
Elapsed Time:  0 00:00:01.76  CPU Time:   0 00:00:01.55
Elapsed Time:  0 00:00:02.07  CPU Time:   0 00:00:01.76
Elapsed Time:  0 00:00:02.14  CPU Time:   0 00:00:01.85
Elapsed Time:  0 00:00:02.12  CPU Time:   0 00:00:01.78
Elapsed Time:  0 00:00:02.18  CPU Time:   0 00:00:01.80

Same system, disks and storage and so on, of course.

And again, I do not have any stats from HP 8.4, but I do
not remember such differences between HP 8.2 and HP 8.4.
