this softether virtual lan for starcraft-remastered are running for one year

[sk911]

Since the blizzard closed its battlenet in China,I build this softether virtual lan for starcraft players.The players can play starcraft on virtual lan.
Some conclutions come to me after one year's running.

My settings:
Cpu:(my server cpu is 5950x 3960x e5 2698b v3,all of them are 16+core)
ISP:1000Mbps download 500Mbps upload
Users' setting:only tcp connection(because the udp is unstable between China different isps such as ChinaUnicom ChinaTelecom ChineMobile)
Softether hub setting: 100% tcp packets loss,only udp game packets allow

1.Cpu useage
When the login users are 200~250,the Cpu useage is 30%~80%(3950x)
2.Lag
When the login users are more than 200+(especially 250+),the lag become unacceptable for games.Ping shows no much lag ,but in game the lag is huge.
