Linux "The London Stock Exchange has said its new Linux-based system is delivering world record networking speed, with 126 microsecond trading times. The news comes ahead a major Linux-based switchover in twelve days, during which the open source system will replace Microsoft .Net technology on the group’s main stock exchange. The LSE had long been criticised on speed and reliability, grappling with trading speeds of several hundred microseconds. The record breaking times were measured on the LSE’s Turquoise smaller dark pool trading venue, where trades are conducted anonymously. That network switched over to Linux from Cinnober technology two weeks ago. Speed is crucial as more firms trade automatically at lightning speed, using advanced algorithms."

I kind of agree. Not only they replaced Windows for Linux, they also replaced the major components of stock exchange software. I think the latter has more impact on performance.

I have a feeling Linux is not the major contributing factor, i.e. replace it with BSD or Solaris and you're unlikely to see major performance drop.

Over the years all operating systems have been tuned for maximum efficiency, it's not the kernel developers, but application developers that write inefficient and buggy code.
