Hello,
Why is there such a big delay on my server http://www.gametracker.com/server_info/80.72.42.38:27048/ ?

It's often 16/16 or 12/16 but the graph works really slow and it doesn't register this activity. I am also using other website to track my server and they show activity much better. Can I do something about it?

The graphs update on an hourly basis and each point represents an average number of players over that hour. If you do not average 12 or 16 over that hour, it would not show quite that high when it updates in the next hour.

Keep in mind that the times in the historical graph represent US Eastern time. If you are in Poland as your profile flag suggests, this would "seem" to be a big delay, though it is not.

Oh, I didn't know it's average, thanks for making it clear.
