L2J Server

Is the online shops operate negatively on the server?
I mean here the consumption of the server, server stability, etc.
I noticed that some of the good servers have disabled that option.
Can little influence on the consumption of the server?
Any suggestions welcome.

offline shops are just player instances, with the advantage that while you is in offline store mode, its client does not send nor have to recive any packet. Its behaviour is more like a npc than a player, and ofc, it does not increase the server resources consumption

L2GameClient#AutoSaveTask need many cpu power.
for example if you have 100 offline shop then 100 login pc same time. 100 run AutoSaveTask same time.

thanks for the info
