How Linux Mastered Wall Street

itwbennett writes "Linux has become a dominant player in finance [1]
thanks to its ability to pass messages very quickly, said Linux kernel
contributor Christoph Lameter. 'The trading shops saw that the
lowest-latency solutions would only be possible with Linux,' Lameter
said. 'The older Unixes couldn't move as fast as Linux did.' One key
attribute was the TCP/IP stack, the configuration of which determines
how fast a message can be passed between two systems. Linux also
offers financial firms the ability to modify the source code to
further speed performance. 'It depends on how daring the exchange is,'
he said, noting that NASDAQ uses a modified version of the Gentoo
Linux distribution. Lameter will discuss how Linux became widely
adopted by financial exchanges at the LinuxCon conference in Vancouver
this week."
