I love to fiddle to see if I can improve on some app, service, or configuration of my server just to see if I improve performance, etc. Example: pFsense....great googlymoogly at the options. I kept trying this or that tut, no joy. So I sat down with the manual, and just did what I knew, Then did a lot of reading, and I did find one or two tuts that actually were, I guess you'd say, 'at my level'. Then I fiddle to see if I can get better performance or to see what one of the thousands of options does. I have leaned heavily on backups from time to time.
