All a bit off topic but..
Milliseconds are now worth a great deal.
In 2010 one large investment bank valued 1 additional msec of latency
between major financial markets at $120 Million per year.
This is in turn driving a lot of new fibre projects along new, shorter
great circle routes with the side effects of bringing long haul fibre to
new places and driving down prices on established routes.
These days the Telecomms industry trend is to quote RTT latency in msec
to 2 decimal places
Some recent projects of interest in this regard are.
(landing in My end of Ireland, due our geographical advantage ;-)
Tokyo London (& NY)
Which will better the current best overland route
Chicago - NY
Which in turn may yet be considerably bettered by Wireless Point to
point (at of course much, much lower capacity and greater cost than
Optical Fibre )
NY - Sao Paolo
Quite apart from better optimised telecomms routes High frequency
trading applications are moving to FPGA's for faster transaction speeds
Like it or not the speed of light is becoming the upper limit
here's a rather interesting paper that analyses the best locations for
trading between markets based on the optimum low latency routes being
Many of these routes are in the process of being built.
