Most the hits on a WordPress blog (or any blog) are on the home page. This requires database activity and processor time. To speed things up, install the free wp-cache plug-in.
It saves requested pages to disk so the next time someone requests the page they get the saved version. thus eliminating much processor and database usage. It is way easy to install. Make wp-config writeable by the server (chmod 777), copy the files in, activate and that’s it. It refreshs pages every hour by default and cleans up expired pages. A true gem of a program.
Also, you might want to delete this line in your template.
