Yes. But bug #22288 and friends are fixed.
I did some comparisons using elisp-benchmark earlier on today. With the
bug fix, the timings were just 2½% slower.
Anything doing compilation (whether byte- or native-), or doing lots of
tight loops will be slower than that -2½%.
Other programs (such as CC Mode) which spend a lot of time in the regexp
engine, or garbage collection, or I/O, will have lost less than that
2½%.
But the main thing is that longstanding bugs have been fixed.
