Hi all, I have a website that gets a fair amount of traffic, but on occasions the traffic spikes are very big. Think 4,000 people on the site at the same time.. Here is my current VPS setup an SSD4 package: Apache 2.4.10 MPM Prefork PHP 5.5.17 DSO + mod_ruid2 Zend Opcache Nginx ((http://www.nginxcp.com/) Memcached Do you guys suggest any other improvements/changes? I noticed at a peak of 4k visitors that I had problems logging into my email through cpanel and editing a post due to a database error. It said too many connections. Is there any way to optimize this as well? Also, would you suggest changing from Nginx to Varnish maybe? Any suggestions would be greatly appreciated!
