Using Debugging Information
Most of the better software has varying degrees of capturing debug information. This is valuable for initial setup, and tuning. For the long term, though, it is best to turn these debug settings off.
Unless you are actively trying to isolate an issue, or tune your servers for better performance, the debugging information you are capturing is of no use. In fact, it probably is not even being looked at. What it is doing, is taking up disk space with logs, and slowing down your processing by having to write to these logs.
There are some packages that do not allow you to turn off, or turn down, the logging level. If you have any of these, then at least make sure that you clear out the log information from time to time.
So, if you have tuned your system to your satisfaction, and are not chasing any issues, turn off that debugging. You may be surprised at how much your performance increases.
