Yes, I see some slowdown wrt 23.2, although not as drastic. Are you
sure both binaries were compiled similarly, e.g. as far as compiler
optimization switches are concerned?
Perhaps not. The 23.2 was not built by me. I picked it because it was
the oldest I have.
Anyway, you may wish to experiment with setting jit-lock-defer-time to
a non-nil value. E.g., try setting it to 0.25 or 0.5 sec, and see if
that gives good results.
I tried setting that to .1, and here's what happened.
I typed C-s C-s (which searched for "honor"). It found the first
occurrence and displayed it without fontifying that area.
Then I typed C-f and got no response. I suspect it had already
started to highlight the other matches, and was fontifying the
regions where they occur.
The C-f was executed after 30 seconds or more.
The current code gives bad results with all settings of that variable.
The code needs to be fixed.
