"I've got the hardware budget left to bump up the memory on the new
system a bit if that'll help and I'm tempted to do it (hence this
thread). "
This seems as an uninformed attempt to solve a problem. If it doesn't
harm - it might work.
Resist your temptation to this "checklist approach" if you seek
insight in the problem. Adopt a methodology as Cary Milsap provides.
Analyse before implementing a solution.
But the temptation to buy more hardware is strong. I remember a
situation where a new and critical application was performing very
badly. The CEO personally ordered a new 8 CPU machine with more RAM to
push performance in order to buy time for the programmers to tune the
application.
The old machine was a 1 CPU machine. There was an increase of
performance between 0 to 2 % (if i remember well) , instead of the
800% the CEO expected.
So if you want to try the RAM scenario, do as you please. But please
measure your performance in response times, and not some hitratio. And
then have a look at the difference in performance.
