Thread: Windows vs Linux execution speed.

Started 1 month, 4 weeks ago by Pretz
I have an application build in C++, which is portable on Win and Linux. It's a communication node between other two applications, and it's using UDP as streaming. The problem is that the entire installation is running faster when this node runs on Windows, and much slower when it's on Linux. All it has to do, is to listen on a UDP port, and sent received data on an other UPD port. But it's ...

Wide open field there. It could be anything from hardware, to cables, to configurations, to having 'Auto-negotiate' turned off somewhere to the protocol stack, to memory, to ... well, you get the picture? Start first by running some simple raw speed tests on both boxes, see how they behave. Note: Run the tests locally in controlled circumstances, not a test site on the net. Even just ...

I cant test it locally, because the other two applications (client and server) are running only on Windows. I tried to test them all on same machine with Windows plus a Virtual Machine with Linux for the ...
