DST Server lags when there is alot of items on the ground

Put 1000+ tooth traps on the ground.  Other items can do this too, this is just the easiest way to reproduce the bug.

if 1000 doesn't lag it, put 2000. etc. until it lags.  Although this isn't exactly the same as playing on the official server, I believe the problem (root cause of the lag) is the same.  So doing this you'll be able to investigate what is causing the lag.
