Erlang is not "real time" in the hard, embedded systems sense, but it does pretty well and has GC.

Here's a bit more information: http://www.erlang.org/faq/academic.html#id55755

I don't know what sorts of 'real time' properties trading systems are required to have - can anyone talk about it with a bit more in-depth knowledge?



I don't know much, but for high-frequency trading, fast is never fast enough. response times are measured in microseconds.

Speed isn't all. The system should be based in algorithms with manageable worst case time.


I don't buy Erlang camp's reports.

A GC will always trash the cache, and that's the worst issue right now in hardware. (If you take out HDD I/O.)
