On my box the current system scores about 50 msgs per second (starting in
memory, of course). While that can be a drag while waiting for one of my
full test runs to complete (one of those scores a message more than 120,000
times, and trains more than 30,000 times), I've got no urge to do any speed
optimizations -- if I were using this for my own email, I'd never notice the
drag. Guido will bitch like hell about waiting an extra second for his
50-msg batches to score, but he's the boss so he bitches about everything

I haven't profiled yet, but *suspect* there aren't any egregious hot spots.
5-gram'ing of long words with high-bit characters is likely overly expensive
*when* it happens, but it doesn't happen that often, and as an approach to
non-English languages it sucks anyway (i.e., there's no point speeding
something that ought to be replaced entirely).
