That's weird. Would be nice to run a profile to see what makes it so slow. From a quick look on the code it just creates a shared memory segment, which shouldn't be that expensive... > 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.

It's probably not that well known, especially as I'm not sure underlying library is well maintained (it has been last updated in 2006 but maybe it's still good and doesn't need any updates?) but I'd give it a chance by at least trying to see what's up. If it proves hard then we may think about dropping it. -- Stas Malyshev smalys...@gmail.com -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: https://www.php.net/unsub.php
