 Hello guys, how are you?
 I think i found something very wired and i not so sure issue connected to
 the core, but it is worth a try.

 I have 3 different machines on Google cloud, dedicated machine for 1
 WordPress site. (e2-micro machine)

 All my 3 websites identical with the same design, theme, plugins and code.

 The only different between them is the language of WordPress.

 The problem is, i am experience overload on all the machines when editing
 a page in the default WordPress editor.
 Even if i only get in the default editor and only refresh the editor (F5),
 i get overload on my machine.
 **I notice jumps of 150mb – 200mb when i refreshing the page.**

 What causing kswapd0 to be triggered on my server and this is look like
 this:

 In the start all the 3 VMs was experience the same overload.
 I was suspect on the post revision + autosave and wp-cron.

 **So, i limit the time of wp-cron and turn off the post revision
 completely + autosave for 1 day in wp-config:**
 define( 'AUTOSAVE_INTERVAL', 86400 );

 define( 'WP_POST_REVISIONS', false );

 define( 'WP_CRON_LOCK_TIMEOUT', 60 );


 This helps a lot for all the 3 websites in general.
 But still i was getting overload on 2 different machines.
 Only in my English, WordPress not experience overload anymore. (this way i
 think isiue is with the language of WordPress as well)

 My other 2 WordPress websites in different language experience overload
 after 24 any time i am editing a page… (the other WordPress is in Catalan
 and Spanish)

 **So for the final conclusion:**
 1. I suspect in Autosave, because issue happens after 24 hours (i change
 the wp-config).
 2. I think it is a language issue too. (websites identical as i said
 before)
 3. In the English WordPress, we not experience the overload (we're still
 seeing 150 – 200mb when refreshing the page, but don't have overload).
 4. Why when i refresh the default page editor it consumes 150mb – 200mb?

 Be happy for your help guys.
