When all servers full we use about 54-70% CPU Usage

I am using 4 cores, so far the performance is still smooth under heavy load, is it time for me to upgrade to more vds cores?

Unless NFo minds that I am using up over 50% Cpu usage :/

It's your VDS so you could use 100% of CPU and not cause an issues. However, 54-70% is high and eventually you could start to see some issues.

Me personally, I would upgrade once I seen 60-65% sustainable CPU and load averages. You could see performance issues on large CPU spikes across all game servers running on the machine. One server requires a ton of CPU abruptly, it will affect other servers currently running normal load, etc.

Internally, our load-balancing kicks in when we hit 40 or 45% peak CPU usage. But I'm very picky about performance, and this might even be too conservative .

That's a low peak, as a server could easy spike that high during a large transmission of some sort. It seems to work well doing it that way, though. NFO most definitely strives for the utmost best performance
