Well, with no specifics on performance of *what*, it's hard to say.
There are certain operations that could be quite a bit slower, yes.
I haven't heard of too many people noticing a problem though.

It's probably worth noting that locale could be at least as much of a
factor as encoding ... but perhaps I'm jumping to conclusions about
what your slow operations are.
