A site I want to optimize is having incredibly slow load times due to increased resource usage (warning in cpanel too). Everything else is perfectly optimized cache etc. Never had this happen before even when the traffic was very high.

Any help appreciated.

Mostly it's because of a corrupted javascript file which is loading simultaneously many times. ANd you maybe have a plugin conflict. I can help you if you need.

this is time to keep eye and pluck the issue,simply use wp fastest cache and rebuild cache ,if response is same then do some
turn off all the plugins and check the response if its been ok then means theme is fine if not then check your theme header file may be lot of out resource jquery or some are used.
seems its ok after turning off plugins then try to turn 1 by 1 plugin and check response
you will find a plugin which may cause for high load
further more try to use 3rd party websites for to check website speed like speed test instead of your local browsing
WP is basically resource suc***r so have to keep strong eye on resource panel

For Caching: W3C is the best one comparing to the others ( will works great if Nginx is installed on the server ).
Mixed with OPCache or Memcached ( should be well configured ).

Anyway, anyone can google them and learn more.

already did that. I am fairly experienced with WP but in this case, the server is running a lot of "concurrent processes" that are causing heavy load.

VPS or dedicated one?
Also for the disk: SSD or SATA or SAS.
Also: Raid 0 or Raid 1... ( Hard Raid will be better then soft )

No sir.
Most of hosting companies use Apache + Nginx or Apache + Varnish.

Apache only is a waste of hardware resources
 
Thanks to all member for replying. Shifted the site to a Vultr server I have. Same results, the "wait time" is horrendous in Pingdom.
 
Cmon man, I told you the reason. There is nothing wrong with your hosting/server. It's theme/plugin fault.

Vultr is good.
Use a VPS with at least 2GB of ram.
Also check your server with "top" and "atop" ( "atop --" for i/o disk ).
Tyese will helps you detects the problem.

By the way, I encourage you to install VestaCP ( Free! ) not cPanel.
And use Apache + Nginx or Apache + PHP FPM.
And you will see.

Totally get that as the issue persists even after switching to a very speedy server. Tried disabling all plugins one by one still nothing. Feel like pulling my hair out at this point. The site also uses a speedy CDN.

Well. No totally true.
It may be true until they share with us some reports like from P3 or a screenshot for "atop -d" ( to check i/o disk as it is limited for VPSs and to check SWAP and Cached memory ) from SSH.

Did you try to make a default wordpress theme active?

I get that you are an a sysadmin, i'm too, but it's really rare that the server is faulty if there is not a huge traffic.
 
Are you checking the logs to see what files are being requested? Had some cheeky competitor requesting the xmlrpc.php file loads a while ago, was making the site and server crawl. Check your logs and see if anything suspicious in there.

As you know, Vultr VPSs are based on KVM ( Openstack ).
They usually limit the i/o disk to 1-2MB/S.
So he may should see what is consuming.
cPanel has a lot of things running on the backend.
 
The weird thing is this site had 700-800ms loading speed a few days back. Problems started since yesterday and I didn't even make any changes whatever.
