> In extreme cases, on purely CPU bound benchmarks, we’re seeing a jump from < 1Gbit/s to 4 Gbit/s. Looking at CPU flamegraphs, the majority of CPU time is now spent in I/O system calls and cryptography code.
400% increase in throughput, which should translate to a proportionate reduction in CPU utilization for UDP network activity. That's pretty cool, especially for better power efficiency on portable clients (mobile and notebook).
I found this presentation refreshing. Too often, claims about transition to "modern" stacks are treated as being inherently good and do not come with the data to back it up.
