I did install and run OnyX recently, since I usually don't leave the PB on overnight. That made a huge overall improvement, and seemed to restore the PB to its original state.
This is a big one. Log writers typically load the entire logfile into memory to write to them or at the very least large chunks, so properly truncated logfiles do help things a lot, especially if these things have been running for months without the maintenance scripts running. (We ran into a problem with a neglected logfile on our web server...one we thought was being properly rotated wasn't, and we found the hard way that Apache will not run with a logfile > 2G...)
I know that if I was working on huge files on high-powered software, with tons of photos, long movie clips, graphics, rendering, etc., I might see a more noticeable difference with the RAM upgrade.
You really only see a dramatic improvement with added ram if you move up from an inadequate amount. At 512 M your system had more than adequate amount of RAM, so until you start doing things that are RAM constrained, you will not notice the difference.
To make a very strained analogy, what you did was the equivalent of installing auxiliary gas tanks in your truck (that you don't drive in more than 100 miles in any direction) and are wondering when you're going to see the improvements...you're not going to see anything until you actually need to use that RAM.
You probably have no practical limit now on how many programs you can run at once...but this doesn't really seem to be much until you look at your dock and notice it's crammed with little black triangles.
