I have a 5,1, 16GB Ram, 512GB SSD and 4 spinners. Boot drive is SSD. When I right click a file and accidentally pause over "Open with" I get a beach ball anywhere from 15-90 seconds, then all is well. The pain is that I can't do anything else in Finder while this is spinning. Any idea what is causing this? One thought I just had is that I cloned my old 1TB drive to the SSD and didn't delete anything. Is it looking at 'Applications' on both drives? Everything else is pretty zippy, just Open With is slow.
