Pages slow to load

I just tried switching off the plugin on the production website. It went from a TTFB time of 7.5s to 800ms! See these images:

Can anyone please help with this? Is anyone else experiencing the same problem?

Question – on page load, does the plugin try to make any kind of connection with S3 on the front end?

Nope.

Is there something more than just loading in the assets from S3 that’s at work?

WP Offload Media Lite isn’t loading the media from S3, the browser will do that, but what you’re seeing is a delay in delivering the HTML to the browser.

Can you use something like the Query Monitor plugin to see whether there are any database issues?

Where’s the database in relation to the PHP server, same machine or another one?

Have you tried turning on WP_DEBUG and WP_DEBUG_LOG to see if any errors are being thrown?

Hi Ian,

Thanks for coming back to me. All sorted. I think we chatted via email…?

Awesome, wasn’t sure!
