I tried Dvorak for a month a few years ago. For me it was just useless agony, not only with key positions but also with app/OS shortcuts that are very much designed for qwerty layout.
I have since switched to a split ergonomic keyboard (Diverge 3) and adjusted the layout somewhat (kept qwerty, but put all the modifier keys in custom locations). That took me about a month to exceed my previous speed. Typing on standard keyboards when needed is not a problem either.

I never cared to measure my typing speed though.
