WordPress performance issues

[theblack]

Hello,

I noticed that the WordPress websites I host on my CentOS 6 VPS have performance issues (slow load time). Do you have any tips on how to improve performance for WordPress?

I also have another website built with PHP and it works great, this problem seems to be only for WordPress.

Here are my VPS stats:


My Web Server is running on Apache & Varnish Cache & Nginx Reverse Proxy.

Thank you!

1- use gzip compression
2- optimize your database
3- use less plugins

I already use gzip compression, even just installed WordPress websites have a pretty long load time.
