I will start this post by saying that I have used Apache for more than 2 years in production environments and I am quite experienced at optimizing Apache to accomplish the goal at hand should it be handling thousands of connections simultaneously to serving dynamic web sites quickly and efficiently while minimizing the memory footprint.
I have in the past fought tooth-and-nail for Apache’s ability to match LiteSpeed Web Server’s speed when serving web sites. Apache can be configured to be nearly as fast if not just as fast as LiteSpeed but the problem is that Apache requires in my own personal testing nearly two times as much memory and FastCGI to come close to LiteSpeed comes out of the box. LiteSpeed claims to serve static content up to 9 times faster than Apache and PHP up to 50% faster. While I won’t go into depth as to which one can do what faster, I will go into why I chose to move my company from Apache to LiteSpeed and what benefits we have seen. If you want to see benchmarks that compare LiteSpeed and Apache I recommend you search Google. Continue reading
