How can I get a better Free Tagging Performance?


I am developing a bigger site (D5) with a free tagging vocabulary. Currently the vocabulary has 16.000 entrys. i have searched with google and on, but I have not found some performance improvement like cache or pacthes.

What are you doing?

I think I am not the first one with bigger vocabulary. Some links or code snippets would be great.
