Performance of C++ vs Virtual Machine languages in high frequency finance

Question

I thought the C/C++ vs C#/Java performance question was well trodden, meaning that I\'d read enough evidence to suggest that the VM languages are not necessarily any slower

Answer 1

Virtual Execution Engines (JVM or CLR of .Net) do not permit structuring the work in time-efficient way, as process instances cannot run on as many threads as might be needed.

In contrast, plain C++ enables execution of parallel algorithms and construction of objects outside the time-critical execution paths. That’s pretty much everything – simple and elegant. Plus, with C++ you pay only for what you use.
