The final stage in speeding up my blog was to add some serious caching to the front of it. This may even have been overkill, because it was already pretty swift under nginx/php-fpm, but cutting out the database connections would speed it up even more.

I had a quick go with the W3 Total Cache WordPress plug-in, but it seems rather biased to running Apache (which I’m not) and I experienced some strange errors that I failed to immediately fix. Rather than wrestle with it, or try other WordPress caches, I decided to get to grips with Varnish. This is something I’d been meaning to do for ages, and of course it isn’t limited to WordPress – Varnish is a fabulous caching solution for whatever site you’re building.

Speeding up my blog

Performance issues aren’t just for high traffic sites. I’m lucky if I get 50 visitors a day to this site, but by using scaling techniques popular with the big boys, I figured I could increase page load speeds, (good for visitors and good for SEO). If I could achieve this and use less resources, perhaps I could even save some money on my hosting bills. I currently run a 512MB VPS on Slicehost, and I’d rather not increase this right now.

With a few days off work, I decided to take the plunge and swap out some of the server tech powering this blog. From the bottom up, so to speak, this was as follows –

  1. Replace Apache with Nginx (below)
  2. Upgrade to PHP 5.3.3 and run as a FastCGI (next post)
  3. Upgrade to WordPress 3
  4. Deploy a CDN
  5. Add a Varnish cache for extra speed

I’ll go through my experience across a number of posts, starting with Nginx. I shan’t replicate any existing documentation; I’m just going to go through what I did and point you at the resources you’ll need.
