Обсуждение: Add slowdown after conversion to UTF8

I've searched the web and can find very little on this issue, so I was hoping those on this list would be able to shed some light on it.
Performance has dropped through the floor after converting my db from ASCI to UTF8. Is this normal behavior on 8.4.x?
I'm mystified as to the problem. Thanks for any input you can provide.

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.
