How much data can Qlog process?
Qlog can process as much data as your CPU can handle. There is no limit to the number of players it will process. My server currently has over 14,000 players in over 25Mb of frag logs (over 1 million gibs!) and it handles it with no problem. As you might guess, Qlog will begin to run a little slower as the number of players increases. Note that the limiting factor will always be the number of players, not the number of frags. Thus, if you have a private server with a few hundred users, you should be able to run Qlog on any amount of data.
