 * Hi All,
 * I am using WordPress for my site with 2.500.000 visitors per month. I used separate
   VPS (GCP) in the same region for WP & DB. This is my spec VPS that I used :
 * WP
    – 6 Core CPU – 15 RAM
 * DB
    – 4 Core CPU – 6 RAM
 * My problem is, the average CPU usage is 30%, buth when our admin is login in 
   WP Admin and update the content (Post or Page) the CPU usage spike into 100%.
   Sometimes even make our site got Error database connection.
 * I tried to search in internet how to speed up WP but got no clue about WP admin
   problem. I have done this to tried to fix it but nothing works significant:
    –
   Using cache (WP Rockets) – Disable admin ajax – Add Heartbeat plugin – Optimized
   DB – Disable and remove unused plugin – Test Avada themes in other WP and working
   fine.
 * Can you guys help me with this issue? Maybe I missed something? And how to calculate
   server needs in term of traffic?
 * Thanks!

 * Hello netizenconsultant,
 * There may be some plugins that you have installed on the WordPress that is causing
   the high consumption.
 * Typically what I recommend, to help find these troublesome plugins, is to install
   a plugin profiler, such as P3 Profiler. This can be used to view the resource
   usage of the plugins and find the ones that might be causing the problem.
 * Configure WP Disable. WP Disable(Plugins) turns off unused WordPress settings
   that consume CPU like post revisions, autosaves, pingbacks, trackbacks, emojis,
   and others. It also has other speed options like loading Google fonts asynchronously,
   heartbeat control and hosting Google Analytics on a local server.
 * Lastly, You may need to consider a dedicated server if the current resources 
   are being overly consumed by the site, even after optimization. Dedicated Servers
   will typically out perform a VPS, as the resources are all physical and not virtualized.
 * Hope this information helps.
 * Thanks.

 * Hello netizenconsultant,
 * Your website has got pretty decent traffic which means it will always be busy
   serving a lot of content. According to me, you are getting 30% of CPU utilization
   as you are using cache plugin and static contents are served from Cache but when
   you log in as an Admin, WordPress has to work on generating new content each 
   time. Can you please confirm if you are using Object Cache. As you are using 
   a VPS server. You should use Object Caching software like Redis. It works on 
   the server level and caches your database request.
    I also recommend you to use
   CDN like Cloudflare which will reduce the burden of serving static files from
   your server. You should also check if you are not using any resource hungry plugin.
   Hope this information helps you.

    Thanks for the 
   suggestion! I tried P3 profiller but the result was changed everytime. There 
   is no specific plugins that always slow down my web.

    Thanks for the
   suggestion! The Redis, should I install it in WP server or DB server? Because
   the high CPU usage is the WP server. The DB was fine. For CDN, is there any recommended
   CDN beside cloudflare? I user Google Cloud DNS so I cant use Cloudflare.
