No plugin is installed, and HDD is SAS 15k, and running raid 10.

But the problem is that someone users is error and other users is normal (load the website is very fast)

[Tsanten]

Same browser?

Do you have some plugin ho interact with your theme?
For what i can see its an incompatibility problem of some plugin with webserver.

[Anik]

if you are using php-fpm it needs to tune the config. like the max children, requests etc.
how is the sites traffic and servers hardware?

depending on your server configuration, you should consider increasing the values. specially the php-fpm one.

You can specific value examples?

that will depend on circumstances, but you can first increase the maxchildren to something 12/15, 5 is really not good for you.
