Admin taking a very long time to load
Logging into my site’s WordPress admin backend take several minutes. The site indicates that it is loading and then just hangs for many minutes before finally loading. It smells like something is timing out, I suspect a plugin, but I can’t for the life of me figure out what.
In order to troubleshoot this, what steps would you take if confronted with such a problem? Turn plugins on and off and see which is the culprit? The problem with this approach is that after the initial slow loading, everything loads normal. Check php max execution times in php.ini? Somehow monitor outgoing connections to see what’s trying to reach something and timing out (how would you do this)?
Any suggestions welcome.
