It doesn’t look like your server has much load there, which is good. And you also have plenty of RAM.

How long is it taking to load?

And are all screens that slow, or is it one screen in particular?


One thing I found.

I Set in server configuration --> website options :

Run CGI scripts as domain owner : No

PHP script execution mode : Apache mod_php (run as Apache’s user)

The situation gets better, Specially in wordpress management. (virtualmin status fewer)

But access to the files on host is limited.

Does that Issue, can help ???

Thank you for reply,

No, This problem not exists in all pages.

Must Dullness (slowly), When the Switch webmin to virtualmin (And conversely).
And virtualmin pages.

Length of time for task mentioned is over 80 seconds !!!

For Example :

  1. I want to go virtualmin–>server configuration–>website options.
    this time for load page is 120 seconds !!!

  2. I install wordpress in the host and I want to install plugin from wordpress management page.
    this time for load and install is 180 seconds !!!
