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.

Short of migrating to Nginx, add:

1.) Memcache;
2.) APC;
3.) the W3 Total Cache plugin; and
4.) and other caching, such as Varnish, for example.

If you're interested in Nginx (but I don't think ZPanel supports Nginx), check out How To Install Wordpress, Nginx, PHP, and Varnish on Ubuntu 12.04.

Varnish is an HTTP accelerator and a useful tool for speeding up a server, especially during a times when there is high traffic to a site. It works by redirecting visitors to static pages whenever possible and only drawing on the server itself if there is a need for an active process. This tutorial covers installing wordpress on a LEMP stack (with nginx instead of apache), and then installing varnish.

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.
