Making Wordpress 2.8.x run faster

This week I performed a necessary upgrade to 2.8.X and experienced some nasty time-outs.
Loading pages was extremely slow.
Here are some tricks I used to make it a bit faster:
1. Add following lines to /etc/my.cnf:
query_cache_type = 1
query_cache_size = 26214400
2. Use WP-SUPER-CACHE Plugin
Just go to wordpress.org and check the installation instructions.
3. Add the hostname of your blog to /etc/hosts
4. Enable default wp-caching by adding following line to wp-config.php:
define(ENABLE_CACHE, true);
Now restart mysql server and the http server.
You will notice an improvement!
