Hi there,
We’re running EE for some years now on a dedicated webserver and dedicated mysql. We’ve also developed our own plugins/modules over the years, so we know all about this great cms.
our site normally receives 30.000/40.000 unique daily visits and the server (apache/ubuntu) handles 1500-2500 users online without any problems. Our SQL server has a stable load of 1-3 and handles 250-450 average queries per second.
Since two days, we’re receiving traffic from some new sites which results in 5000-6000 connections and around 1000+ queries per second. But our SQL server keeps crashing with Cache Dynamic Section Queries disabled. We had to enable it to get everything stable again, but it was disabled from the beginning (we’re tracking the views of videos, so we need it).
The difference is huge: running with Cache Dynamic Section Queries enabled versus disabled. Disabled isn’t an option at the moment, server load increases to 50+ and the site stops functioning.
What’s the effect on the system switching it? Which features/queries are ignored when it’s enabled?
Hope someone can explain it to me, because we really don’t want the cache to be enabled. Stats/views aren’t count anymore…:(
TIA!
