Hi internals,
I've recently found out that compiling PHP with --with-mm has a massive
negative impact on PHP startup performance (approximately 3-4 times
slower), to the point that our CI got approximately 2x slower overall with
it enabled. This is not great.
As I only found out about the existence of this session backend recently,
I'm wondering how widely it is used, and whether we wouldn't be better off
dropping it from php-src. The performance characteristics make it a pretty
big foot-gun.
Regards,
Nikita
