For me, the first one is slower: about 5 to 6 sec. The second
occurrence takes maybe 3. Stefan, what's your timing?

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?
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.
