I have two sites hosted on the same server machine in the UK with a decent host (KRYSTAL)
my main WordPress admin console takes ages to load on my much larger site ([the5krunner.com](https://the5krunner.com)) than my other one that I won’t name. The latter one loads almost instantly.
Both are properly cached with litespeed to about as good as i can get them
My main site has vastly more posts, quite a lot more plugins (57, with 35 active) and hosts ads. I don’t think the latter is relevant to the admin console loading.
Searching through posts for text is also quite slow
wp\_posts is 928,144kb
​
I’ve used Litespeed to convert all tables to InnoDB
any ideas what I can do to speed up the load?
thank you in advance

Try installing [Query Montitor](https://wordpress.org/plugins/query-monitor/). This plugin will help you diagnose what might be slowing down the admin area. Be sure to disable the plugin when you are done.
Could you check your console (browser dev tools)? Errors may be present that can help you track down the issue.
There may be a plugin slowing it down. Turn off all plugins and turn them on one by one until you find the culprit, if any.
Keep WordPress and all plugins and themes up to date. An update may fix your issue.
You are probably running too many plugins. Try to reduce and remove what’s not needed or build it with ACF.
Also it is possible that you’re hitting the memory limit on your server. If you can, try to add more memory. WordPress DBs use a lot of memory.
These are the most common reasons for slow admin’s dashboard, you can try to see if some of those are “culprits”:
Low WordPress memory limit
Many dashboard widgets
Resource-heavy plugins
Old PHP version
WordPress Heartbeat
Slow database (e.g. too much junk in it)
Too much content loading
Overloaded server
CPU issues (e.g. high CPU resources “hungry” plugins)
Object cache
Enabled cache for the admin’s dashboard
wp-admin/wp-login.php pages attacked by bad bots
Post revisions and autosave
Not using CDN
Plugins’ data sharing
Hotlink protection

The amount of stored data is irrelevant (unless your disk is full). Have much ram/memory does your server have?
