Server CFG Settings

Im currently running two Arma 3 Altis Life Servers on the Intel Xeon E3-1271v3 Dedicated Server package. My first server is the one that almost fills up (70 - 90), while server two might get 10 people.

Once it gets over 60 players its constant red chain and lag and desync. Itll spring up to 80ish players when everyone connects (over a span of 5 - 10 minutes, not all at once) and then fall back down to 50 or 60. Because its unplayable due to the desync. My SQL Database and the servers are on the SSD.

Could I please get some help with tweaking these settings to better fit my 100 slot main server. If the settings could handle it, I would have no problem filling up server one and halfway fill up server two.
