troubleshoot performance issues?
how do i diagnose if a plugin or a page has caused my back end to come to a crawl? and as a result my frontend is slow. i know this because another textpattern site on the same server is working much faster. i was doing a lot of development on test pages last week. i’m worried i added or did something that caused this.
other than that my host claims nothing is wrong, how can i run tests to confirm if they have caused some problem for me?

Re: troubleshoot performance issues?
My approach to this sort of troubleshooting is not very sophisticated, but based on your symptoms I would probably start by deactivating all plugins, seeing if the back end speeds up, and if so, reactivate them one by one. Of course deactivating plugins is bound to result in errors on the public side, so ideally remove the site from public view somehow (rvm_maintenance, perhaps).

I am looking into a dns flush on my local network at the moment. Thanks for your reply!

Re: troubleshoot performance issues?
What do your runtimes say? You can find runtime information at the end of the frontend pages when the site isn’t in live mode.
If you find a particularly slow page, and need to investigate individidual blocks of code to find the source of slowness, you can try out rah_runtime. It can give runtimes from specific parts of the code.

Re: troubleshoot performance issues?
thanks that looks like a great plugin! is it possible that when you work on a website on a network so often, some sort of cache clogging happens?
