This is actually a trading platform but if you can run the exchange on the JVM you could certainly write a client for it on the JVM.

I had seen that, but Martin Fowler is not whom I would have thought of as deeply familiar with low latency and JVM performance under stress.

I will be looking into that platform, but I see one caution flag: LMAX is a new retail financial trading platform. As a result it has to process many trades with low latency. the key word being "retail". I am wondering if retail's version of low latency is in seconds or tens of seconds.

I think you're off by an order of magnitude or two.

Our fund doesn't really worry too much about execution speed and we'd only tolerate low 100 millisecond latency. 10's of milliseconds is what we'd prefer.

Many firms want to be lower still.

Thanks for the note.

Couple of questions.

1) Do you consider yourself retail? I would have not considered a hedge fund retail.

2) Can you say if you are colocating your servers?

3) Can you say if you are using JVM in a latency-critical application?

I am working on a benchmark, building a fake exchange framework as a platform to test relative performance of various languages, where various includes Lisp, C, Java and possibly others.
