I just recognized that my newest wordpress version that I have installed on my server supports the google gears local server. This allows me to download my most used parts of the blog software directly into the google gears local server. This server then serves as a communcation part between my real webserver and the locally cached files. The often used files will be directly loaded from local so I expect a huge performance improvement… I will keep you posted.

What is google gears?
