For real server work the defacto sysctl_somaxconn limit seems inadequate:

    Experiments with real servers show, that it is absolutely not enough
    even at 100conn/sec. 256 cures most of problems.

What in the world is a server running on multi-GHZ cpus doing such
that it cannot accept() fast enough to keep up with a 100 connections
per second?

We were handling that just fine 10+ years ago.

The math simply doesn't add up.

Either your numbers are wrong or the server design is brain-dead.
