Session storage - Too many active connections #174

Open dandrikop opened 4 years ago

dandrikop commented 4 years ago

I'm using this module for session storage of Magento 1.7.0.2 at Redis. I have noticed that there is often a high number of connections to Redis server. Could pipelining mitigate this situation? If yes, can this be configured via the Magento file app/etc/local.xml?

Pipelining is already used and would not affect the number of connections. Are you thinking of persistent connections? This could definitely help.

Another thing you can do is use a proxy like HAProxy to basically act as a connection pool to offload managing a large number of connections off of Redis. However, you shouldn't have a need for this many connections unless you have lots of app servers and a very very busy site.

Is it a situation non persistent redis connections performing better?

I wonder the situation could be the reason of not making persistent connections a default setting.
