Linux and the New York Stock Exchange

Interesting factoid:

"NYSE's systems run under high pressure and tight constraints. They
process some three billion transactions per day - more than Google
does - and those transactions need to execute in less than one
millisecond. Customers can switch to competing exchanges instantly and
for almost no cost, so if NYSE's systems are not performing, its
customers will vanish. A typical trading day involves the processing
of 1.5TB of data; some 8 petabytes of data are kept online. And this
whole operation runs on Linux... Downtime is to be limited to 90
seconds per year."

I would concede this is a bit more hard-core than my Asus netbook
running Debian Squeeze... :-)
