Nice job, Panic. Transmit was getting some “stalled” errors to some sites last week, so I paid for Interarchy 6.2 and it was even slower. Now Panic has released Transmit 2.5 and they fixed things like dragging a large list of files (which used to stall the Finder for 20 seconds).
I ran my upload folder test, an album of photos. The results (the first two run back to back a week ago, 2.5 ran today)
Interarchy: 12 minutes Transmit 2: 8 1/2 minutes Transmit 2.5 6 1/4 minutes
