Craft incredibly slow site performance

Question

I am experiencing incredibly slow site performance. This extends to loading the control panel (/dashboard, /login).

This only happens when I put the site on to my hosting, locally using MAMP it runs quickly.

I have done the following which are recommended in other posts:

• upped the memory_limit to 512M
• used (% cache globally using key 'entry-' ~ entry.id %}
• used eager loading for image assets
• Disabled/enabled plugins

Can someone please help?

Answer 1

It turned out this was the culprit. Craft was doing a deprecationerrors query (https://github.com/craftcms/cms/issues/2539).

Turning devMode to false fixed this.

Hope this helps someone...
