Is there some research resource/group working on benchmarking of software products out there with automated trading and goals of "Advanced alpha generation and execution strategies" incorporating low latency data of the order of milli/micro/nano seconds ?
The fastest systems out there are mostly custom built hardware solutions and even the off the shelf solutions are evolving very rapidly right now. There is a company call Correlix which provides latency measurement of trading systems with extremely high resolution. I have not needed their services and thus I cannot comment on how effective they are.
One thing to keep in mind is that measuring milliseconds and nano seconds is very different and just because something is good a benchmarking milliseconds does not mean it will be good at nanoseconds.
