Yes, been a while - things are indeed going well for me! Hope the same is true for yourself.
I suspect the reason you're seeing no problems is the small catalog size. A large part of the performance problems in the current version is an inefficient database design, I reckon. I'm speculating, but when I first installed LR2, I had no problems with performance. It was only after my catalog grew to 40k+ images that things started to really hurt.
I ran the catalog optimizer a few times, but to no avail.
