Re: OT: high frequency trading

Keegan,
You may a great point. And frankly your point is Cisco's argument why the
Nexus platform should still be considered for the High Frequency/Low Latency
trading. So you right, .. once you've squeezed all the microseconds out of
the switch, and your "race to 0" is complete, it makes no sence to be
2microseconds better from one switch to another when the application still
adds 1millisecond of latency (more like a couple of milliseconds or even a
second).

But trading strategies out there are addressing that with
numerous optimization techniques on the software & even server architecture
side. Finally this is where if you application is still that slow..
Infiniband? Hummm... Enough said.

Finally.. be advised.. most of this "advantage" on the latency side is
really played in the 10Gb arena. How many companies are serving up 10Gb of
data for consumption? Yeah, yeah, heard the serialization effect between
10Gb and 1Gb but seriously if your only pushing 1Gb of date on a 10Gb nic,
how much latency are you truly saving to the application?

Great topic, but really only Financial Services and High
computing environments are that concerned with shaving off microseconds. For
the rest of the world, if you get your network to be milliseconds faster,
your the man. Cause their applications are still running in the seconds
world. :-)
