Tweaking a web server with Nginx

A few weeks ago, I started playing with nginx as a replacement for Apache. The exact reasons I decided to do this are a bit unclear, but I think it had something to do with me playing with node.js and MongoDB. The initial setup was pretty smooth and the configuration files are much easier to understand than Apache for my sites. However, I also decided to offload the PHP processing to php-fpm and that’s where the problems began. My VPS is pretty lightweight and doesn’t have a lot of RAM. My blog was running out of memory all the time and php-fpm stopped responding.

After a lot of tweaking to reduce memory usage, I managed to stabilize the system and get much faster response times for my blog; it doesn’t get a lot of traffic, but I think I’ve done a decent job with performance. If I ever get hit with a massive load, I’m sure my server will keel over.

Is there a real reason to use nginx vs Apache? I’m sure some people will say yes, but for me the jury is still out. Things are going smoothly, but was it worth the trouble? I have no idea.
