Hugh page sizes

Thanx for a great plugin, i really like it. However, it seems to generate an enormous amount of code in the page source. I have about 100 different categories at the moment, and just the .html file alone is over half a mega byte in size! Since i’m planning to have thousands of categories, this can not continue of course. Do you have a solution to this problem?
