Performance standpoint for QNetworking and QJson classes

[Peppy]

Hello guys, I do wonder, what's the performance of Networking and JSON classes? I may need it for HPC so I'm wondering whether I should use Qt or I should use something else (CURL, libev, ZeroMQ).

Thanks.

Hi,

You should give more details about your use case but there's one thing that you'll probably have to do in any case: benchmark to ensure you use the solution best suited to your setup.

In that case, you might be already be a bit to high-level in your research. From what I know about that matter, you need dedicated hardware as well as highly optimized OSes and software stack to run at that speed. So again: do benchmarks.
