Yes, comparing to DMA is apples and oranges comparison, but gives an idea of the relative
gap in performance.

A better comparison would be to an alike product such as NCache. They claims 20K wps*, thus
20 times faster than my ignite results, but obvs I'd have to compare using my scenario for
a valid comparison. But this is more like the kind of gap in performance I'd expect vs DMA.
But then NCache product is also quite different from ignite, so what to say?

Email received from outside the company. If in doubt don't click links nor open attachments!

Glad you met your requirements. I think it is not fair to compare Ignite with direct memory
access, so I can't really say whether this is a good result or not. In your case .net process
starts a java process and communicates with it via JNI [1]. Also Ignite stores cache data
off-heap, which requires serialisation [2].
