Re: Debian latency test

[danwe <daniel.wenninger92@gmail.com>]

I do have Xenomai 2 with RTnet and Xenomai 3 without RTnet. I have tested "latency" on both to see how fast the Kernel can react to a request. In that context I do not want to measure how fast e.g. real-time udp frames will be. I just need to know how fast the Kernel could be.

This measurements will be meaningless unless you have a
real time enabled kernel. The kernel does not provide
predictable responsetimes without rt.
