Haven't tried it myself, but doing a quick google, netmap works fine in a virtual machine. Back in 2013 vmware 5.5 was pushing 7.5 million pps with 8 10GbE (and a lot of network optimizations between 5.5 and 6.5) https://blogs.vmware.com/performance/2013/09/line-rate-performance-with-80gb..., and machines are faster now, 40Gbe and 100Gbe are more common, etc... but how many people is that a bottleneck? Networking between vms on the same host are already faster than going out a physical nic. What level of performance do you need that doesn't work in a vm? ________________________________________ From: David S.

Hi, How about "kernel bypass" to increase the network performance? In my case, I installed netmap to increase the network performance and I'm not sure if it's work on virtual machine.
