Depends always what do you need, i would always choose OpenLiteSpeed Server for my "small" personal Websites, but Litespeed is an event-driven async I/O server with a few threads / processes; which means it is faster than Apache and consumes less RAM/CPU than Apache. It is a commercial product, with a nice web-GUI for most administration tasks. It cannot do everything that Apache can, see the Litespeedtech site for details, there is a downside however, Litespeed costs money. The standard version is free (which is what I use), but it caps max concurrent connections.
In older benchmarks it performs better which in my experience is true, but at the same time tuning Apache can get close to similar results, but the LSAPI module is pretty unique (similar to fast-cgi) and works well, at end of the day its up on you what do you want to use.
Exactly, listen to
