Unless you have reconfigured logging to use appenders other than the console and file appenders, I rather doubt that it if logging that is causing the slowdown. You should look in the server log, logging takes place at the debug level there, it might give you a bigger clue as to where theissue might be. Also, in general it is not a good idea to assume that because there is a significant pause between log entry A and log entry B, that the task identified by log entry A used up all that time! Task A could have taken 10ms, and then some other task that doesn't log anything might have taken up the intervening time.
