hi brian, i notice this thread was last active over a year ago.. so i thought it was about time for a recap (in light of the fact that documentation for pecl/memcache and pecl/memcached is sometimes not always up-to-date) --
1) has the persistent connections bug in pecl/memcached been fixed , and if so, is it now stable (i.e. wud u recommend using it in a production environment)? what release/version? 2) in the past, you've recommended using pecl/memcache 2.2.x for persistent connections with a workaround -- is this still the case now? is the workaround still necessary? does that workaround now address the maxing out of memory? 3) persistent connections are generally recommended but can usually cause problems with buggy client implementations as is evident with the php clients.. do u still recommend them? 4) from some of your tests, what is the performnce gap between using persistent and non-persistent connections in either client? is it large enough to warrant a trade in of a larger memory footprint by persistent connections for the performance gain? put another way: would you absolutely *not* recommend non-persistent connections from a performance standpoint? 5) lastly, and slightly off topic (apologies) but relevant, knowing as i do that you use mysql, wud you apply similar logic to connections in mysql using PDO? feel free not to bother with this as it's not the right forum :).. just though i wud drop it in.. cheers, -m.
