Speeding up a Wordpress install

Hi guys,

I'm working on putting together a guide on how to 'speed up' Wordpress, for my own personal use in future projects, and also to disseminate to the community. In my research, I couldn't really find many definitive resources on everything you can possibly look at to increase speed without compromising design and security, so I've decided to make one.

As such, I'd love to hear what you do to spool up your Wordpress sites quicker.

Some things I'm already including or researching:

• Reducing script & style clutter: working on guides and some code snippets to stop plugin's scripts and stylesheets from loading on pages they're not needed, and collating and minifying resources where possible.


• Compressing images, namely with the smush.it plugin where I've found a lot of gains can be had.


• Speeding up server response time with GZIP and site/database caching.


• Setting browser caching.

A lot of this can be done with the W3C caching plugin, but I'd like to delve a bit deeper and explore other options.

Cheers!

Matt
