JDBCAppender configuration

Hi everybody,

I am up to build a coocon webapplication, and I am using the 
JDBCAppender for logging. It works quite well. My only problem is, that 
when I switch on the loggin in debug mode, my application is as fast as 
a snail because of the heavy database traffic. How can I solve that? I 
need the debug mode, because on other modes like info or warn no 
interesting log events are logged. I want to log the database actions, 
so that it is possible to monitor all database changes by the 
application. I heard something about filter possibilities, but could not 
find any documentation. Do I need to write my own appender or logger? 
Which tutorial do you suggest?

cheers
Johannes
