Don't get too impressed here by finance. Almost everything we're talking about here Linux Kernel Developments, SolarFlare (or Mellonx), core isolation (cpu set) was invented elsewhere. Finance merely buys it; it's a great client of all this tech. The only vaguely created-in-finance thing he/she references but then not even by name is https://martinfowler.com/articles/lmax.html which comes from ring buffers coming from CS EE networking itself.

Never heard of LMAX; looks like a Java thing.

Nobody said finance invented anything. But high performance demands produce similar architectures everywhere.

LMAX is a java thing. It's high speed, low latency messaging system used a betting facility in the UK somewhere where in certain betting situations, the number of messages drives up explosively high, and need to be well handled. Thus high, high speed and low latency with reliably low latency were key.
