Rgarding the Apache2 Logging to MySql HowTo

[Mosquito]

Very nice tutorial, this is what I've been looking for - though for CentOS. I'm sure I can adapt it as required. However, my question is, does logged to a database instead of a file show any sort of performance issues?

I currently have an environment with several virtual hosts - all of which I would like to convert to a DB to log, for both access and errors. Should I expect any sort of performace hit when I convert to a database to log these errors?

Each of these existing sites is database intensive in its own right. Will this cause problems?
