This is the vCPU usage reported by XenServer. http://puu.sh/dkRqH/6158526e22.png
The left side prior to the drop is running 128579. The right side is running "arma3server_performance_136v1"
After 90 minutes server uptime with 50 players, we were seeing 20fps.
After 90 minutes server uptime with 63 players, we see 23 FPS with 75% CPU usage reported by Windows (running arma3server_performance_136v1)
There's definitely an improvement to server fps in "arma3server_performance_136v1" however still not as much as we'd like.
