Hi, my Alfred (Build 214) is very slow when typing something. It freezes after every letter I type, sometimes with a spinning beachball.
I use a Retina MacBook Pro 15" which is running 10.9 Mavericks GM. I already did a "Clear Application Cache" and "Rebuild OS X Metadata".
I recorded a video - its showing me typing the word "test" in normal tempo, waiting until alfred catches up and then hitting the backspace-key 4 times. This is all real-time - as you can see alfred freezes after each letter:
