This is also referred to as journal caching, if you're searching for
information on it. Its activated with the JRNCACHE(*YES) function in
CHGJRN, once you purchase the option. In summary, journal data is cached
into memory before writing to disk in larger chunks, rather than making
sure its written at every change. It makes a big difference on journaled
file write/update performance.

Yes, we've already gone to SSD, Rob, so that particular ship has already
sailed. :) However, I am unfamiliar with HA Journal Performance. We
use MIMIX; I wonder if this is something I should be looking into.
Heck, for all I know we already have it, but it definitely sounds like
something I should look into.

Sometimes throwing money at hardware isn't always the answer. Our

a
much larger return on investment would have been to buy the "HA Journal
Performance" option as part of SS1. I daresay it will be a rare
consultant who can pinpoint WHY you might need that and predict how much
it will help.
