First let me say that FARR is one of the best tools I've encountered in a long time.

Like many, I have found the startup delay to be a bit of a problem, particularly since the first few keys I type might be lost between pressing the hotkey and the window appearing. (Yes, I know this will mostly be resolved if I turn off history...but history is useful!) So I intentionally wait a second after hitting the hotkey before I start typing.
Anyway, I'd been using 1.09.05 all this time. I just upgraded to 1.13.01 (noticing that the changelog mentions that an attempt has been made to improve upon this issue), and it's DEFINITELY slower for me, meaning even more keys will be lost unless I wait even longer.
I reinstalled 1.09.05...faster again. Reinstalled 1.13.01...slower again. I repeated a few times, and it was always the same.
So...I'll go back to 1.09.05 and stay there for now! Just wanted to pass this information along. FYI, I'm using Windows XP SP2 on a 1.7GHz machine with 1.5GB of RAM.
Do you keep a link available to older versions? I want to recommend this tool to friends, but I'm less inclined to recommend 1.13.01 than I am the 1.09.05 that I know is faster.
Thanks again for your great tool!
