With warm Tor directory caches it's surprisingly fast - fast enough to be
usable and I'm a notorious stickler for low latency UX. If you want to do
LOTS of lookups so you can cross-check and merge their answers, that's
slower of course.
With cold Tor caches it's indeed too slow. However, reaching "tor by
default" is a part time hobby of the bitcoinj project for a while now and
there are plenty of ideas for how to make things fast enough. For instance,
using a cold cache whilst simultaneously refreshing it in the background,
doing nightly refreshes when charging, lengthening the expiry time, and the
Tor guys I believe want to implement directory differentials too which
would also help.

That seems reasonable for Electrum. I don't strongly care about these
protocols myself (and Justin knows this already), but whatever is decided
should give maximum freedom to wallet developers who disagree with you and
wish to explore other tradeoffs.
