> None of the slowness on my end approaches any of the horror stores in these threads, but for me, opening the program from a cold boot takes long enough for the wait to irritate me, the first time I save any file after opening the program takes a second or two, and opening a new window takes a second or two.

How this isn't considered a horror story is beyond me. I'd consider that sort of latency over a the network to be awful, let alone for a local editor.
