well enough to have an educated opinion on where the bottlenecks might
be. (I've been learning from reading this blog post and comments
however, thanks again to ...
Hi Bruce, Thanks for your informative post. I'm skeptical that posix
emulation is the bottleneck for these capacity tests. One can run iperf3
-c localhost and iperf3 -s to check. CPUs tend to run sub nanosecond and
from internal cache so this should be fine and off board network i/o is
