Does persistent connection help on anything?

[vinerz]

I am getting around 4k AUTH requests on my Redis instance per minute. I was thinking about enabling Predis persistence in order to drop this number, but as I can see inside object-cache, there's no config option to set it before the connection happens.

First of all, will a persistent connection work with the way the plugin works today?
Will this help on anything or is it just a non effective approach?

Thanks for this awesome plugin,
Vinicius

What driver are you using?

I am currently using Predis v1.1.1

What are the specs of your Redis server? And are you seeing any particular metrics maxing out? Even small instances usually handle thousands of requests per second without any issues: https://redis.io/topics/benchmarks

Generally we can add persistent connections to the object cache drop-in, but that might lead to other, new issues that are generally hard to debug.

Another idea might be looking at your server with Blackfire and see how much the AUTH requests really slow down your site.
