No, it’s not. Something is using up too much CPU. Try disabling all of the plugins and enabling them one by one, see which one is causing issues.

<b>“I installed … Ubuntu 12.04 x64…”</b> <br> <br>Do you have 4 GB, or more, of memory on your server? If not, you’re better off with a 32-bit OS. <br> <br><b>“… cause it must not be over 2-3 seconds.”</b> <br> <br>Why do you say that? <br> <br>Check out <a href=“https://www.digitalocean.com/community/articles/how-to-install-wordpress-nginx-php-and-varnish-on-ubuntu-12-04”>How To Install Wordpress, Nginx, PHP, and Varnish on Ubuntu 12.04</a> and the <a href=“http://wordpress.org/plugins/w3-total-cache/”>W3 Total Cache</a> plugin. <br> <br>Also, WordPress best-practices recommend a CDN for static content, e.g. a 2nd droplet or Amazon CloudFront.

Hi, <br> <br>Thanks Pablo, I said that because the last couple of times Wordpress ran without problems, but now, on the same stack with 1GB memory, it has problems. <br>See: <br>http://prntscr.com/2ch982 <br>http://prntscr.com/2ch9q9 <br> <br>I am saying this because friend of mine uses 1GB RAM droplet with no latency almost at all, on his Wordpress site. <br> <br>Is Varnish a good solution together with W3 ? <br> <br>Ty, I will try W3 TC, which noticed on many forums, but primarly wait for many responses here, so maybe someone with same problem will answer. <br> <br>Bye and many thanks Pablo for fast response.
