Hello. In folder "Soldat.ini" I found the option "LogFilesUpdate". What is the best value where you enter?
/Edit
One more question:
What could cause lag on the server?
This is the time soldatserver will wait before it writes stuff in logfiles.
You can test if it affects the lag by using different values or disable logging.
You can find the default value in the soldat.ini (just download the clean server file).
It is currently 3600 if you remove that ini line.
