I’m trying to help diagnose possible server/performance issues and I know the client is making use of Squid caching proxy. They have a number of production servers, and I suppose squid routes traffic and caches content or something like that. This is the first I’ve ever heard of it.
My question is: is it possible something like Squid may interfere with any EE-based caching (tags, templates), or may interfere with anything EE may be doing? I get 40-second+ load times on some pages that should be 1-4 seconds, tops. I would think if Squid is in place and it was actually working…I’d never see a 40 second load time on a page (which I just experienced on their site).
I’m more of a front-end guy, so if I get too deep in the server stuff, my head starts swimming.
