Issue What is Wait Time on Pingdom

[VirtualCed]

Hi there,

I'm hosting Wordpress on Linux server on SSD, 32 Gigs of ram, a lot of free ram, a lot of free CPU resources
But the customer complains about the speed. (not a bandwidth issue)
My server use the Plesk 17.8.11 Apache PHP 7.2.x nGinx as front end accelerator

Where should I look ?
I don't think it's WP related as it seems to wait before the wp starts to load some stuff'

Thanks to help me

Regards

The "wait" time is indeed the time that the PHP script(s) of the website need(s) to render the page until the server can start to send the rendered page back to the browser. If your wait time is long with Wordpress, the WP website is probably using a badly programmed theme or plugin or is waiting on external sources to complete the page building process. The wait time is of course influenced by the CPU load and CPU speed, but long waits are almost always caused by bad scripts.
