I haven’t run things under ESXi so I don’t know what sort of overhead that adds.
Zeroshell is basically just a GUI front end that configures a pretty basic Linux system. And the network traffic management (routing, net balancing, etc.) is all done in the Linux kernel. From what I’ve read and experienced, Linux does a pretty efficient job of that. Not as good as high end routers with hardware acceleration of traffic classification and packet forwarding. But pretty good for a general purpose operating system.
You have faster Internet connections than I but I can achieve 25Mbps using a 500MHz Net5501. Not sure of the CPU load at that point because all my Internet provider claims is 20Mbps so I wasn’t looking for things that could be slowing down my connection.
How does ESXi deal with virtualized network interfaces? is there OS overhead there?
