Getting high wait time of server

This particular reason is why WordPress.com (the inventors of WordPress) dropped Apache in favor of Nginx. You can get better performance on a 512MB droplet running Nginx (w/caching) that what you’re getting now. <br> <br>Short of migrating to Nginx, add: <br> <br>1.) Memcache; <br>2.) APC; <br>3.) the W3 Total Cache plugin; and <br>4.) and other caching, such as Varnish, for example. <br> <br>If you’re interested in Nginx (but I don’t think ZPanel supports Nginx), 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>.

Also, by using a 64-bit OS on a server w/less than 3GB of RAM, any performance benefits that you might gain from the 64-bit operating system are offset by having less memory available for buffers and caching. That’s b/c processes can require significantly more memory on the 64-bit architecture.
