How Linux Took Over the World of Finance
summary
History shows Linux wins finance by allowing in-house kernel tweaks, kernel-bypass and ultra‑tight networking instead of closed OSes; adoption peaks around 2007–2009 as traders hot‑rod systems, brokers follow and exchanges lag five years. Key tooling and practices: DPDK and SPDK for direct NIC/storage access, aggressive multicast and network-stack patches, handcrafted assembly and C++ for microseconds of work on water‑cooled, colocated rigs. Trading cycles run <1 ms locally while global signal round trips take hundreds of milliseconds, so gains must outpace physics.
