Re: [perl-chi] Feature request - setting of namespace from method (not only from constructor) (#7)
Jonathan Swartz
It depends on the Cache::Memcached::* client. Regular Cache::Memcached will do the right thing and use a single socket. Cache::Memcached::libmemcached will use a different socket every time. Don't remember what ::Fast does but it's easy to test.
I wrote an extension to Cache::Memcached::libmemcached that reuses the same socket which I've now remembered to contribute back. :)
