Hi, Thanks for that observation. I increased cache test to 100,000 entries and the average write time is far better at around 23K wps. It seems like a lot of latency on the first few hundred writes.
Do you have any benchmarks published?

I think that comparing steady state benchmarks of multi-million operations versus 500 operations is misleading. 500 operations is probably not enough to gain full benefits from e.g. JIT.

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? regards, John http://www.alachisoft.com/ncache/ncache-performance-benchmarks.html -----Original Message----- From: Maxim.Pudov <[email protected]<mailto:[email protected]>> Sent: Friday, April 26, 2019 3:17 PM To: [email protected]<mailto:[email protected]> Subject: RE: cache update slow Email received from outside the company.

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].
