Give us the ability to disable many of the useless logs

I always wondered why all these unnecessary logs are being shown in gameserver and being logged in the log file? Like party exp logs/item dissapear logs/statoption/monster item drop logs and others are not needed on a stable productive server, they just using extra resources for nothing.
In theory by disabling these super unnecessary logs wont the gameserver perform slightly better? I think it will so why not to gain all the performance we can get rather than wasting resources on logging down tons of log lines that are never useful unless we are debugging. 
Please consider adding an option that will permanently disable each log we want from being shown in gameserver and written in log files.
