Hello, I'm trying to do some initial benchmarking on a rt-kernel versus a vanilla kernel. On the rt the results are stable in between test runs using the following command: cyclictest -t 1 -p 80 -c 1 -n -i 10000 -l 10000 However, using the same command while running the vanilla kernel, I get very varying results. And I would completely understand if it was due to increased jitter. The thing is, the jitter is very low (0% load) but the average times varies from 600 us to 6500 us depending on when the test is initiated. I imagine this might have something to do with not having high res timers in the vanilla kernel. If that is what's causing my problems. What is the best way of comparing the two kernels? I would be much greatful for a few pointers!
Hi Tobias, What kernel versions are you testing out?
