I hear there's FPGAs for that.... what drives me nuts about these
discussions is that custom silicon for trading platforms is all but
inevitable, and will save tons of space and power utilization to boot.

Madly trying to focus on lowering latency in a general purpose OS so
much just to compare two numbers and execute a trade is silly when in
the end it'll be implemented in a discrete circuit.

This stuff is special purpose, so let's treat it as such.

Lowering latency is a good goal, don't get me wrong, but the extreme
goals set out in these cases is for a very specific small group of
users.
