I started using this in December 2015 on the recommendation of a developer in the GenesisWP Slack channel. It's been invaluable in calling attention to PHP warnings, examining event actions and filters, evaluating page templates in use, identifying page conditionals in effect, and providing feedback on number of database queries. It shows the firing order for every action and filter used on a site, and all the SQL database calls. Don't know enough about the latter, but I'm sure in time, that information will become useful during troubleshooting Thank you JB for creating and maintaining this PI!

Not working on page with Fatal Error : memoryu limit
By , for WP 4.4.2

I used it especially to debug a problem : "Fatal error : memory limit"
But it looks like this profiler does not debug if the page is not fully loaded.

In my case it shows nothing..

So good to optimize what's not working, not good to debug what's not.

In the last 5 minutes, this plugin helped me find some queries, which were easily cacheable and taking 800ms! GOLD!!

Also, it showed me some places to optimize some of my own plugins. GOLD!

5 GOLD STARS!!!!!!!!!!

Incredibly Useful Tool

If you have to work on a site that a) is large or b) is old or c) you have taken over from some scrub-lord developer, you shouldn't leave this page without installing this plugin.

It is particularly useful for diagnosis of issues and the collating of meaningful information and statistics. I've found it's the only thing that has been able to assist me with an intermittent issue that occurred on a site I took over development.

I will probably use this on every site I develop in the future too.
