In addition I cherry-picked 3c955b407a084810f57260d61548cc92c14bc627
in order to compile on newer distros.
Thanks.
Here is the result of cyclic test on one machine
sudo ./cyclictest -t32 -p 80 -n -i 10000 -l 10000
policy: fifo: loadavg: 0.00 0.00 0.00 1/541 3759
T: 0 ( 3728) P:80 I:10000 C: 10000 Min: 7 Act: 104 Avg: 114 Max: 470
The numbers are weird. How does that compare to older kernels on that
machine with the same test?
Note this was on a machine with a straight Fedora install, and no -rt
packages or tuning. That being the case, the numbers are no better or
worse than recent -rt kernels. I can get you numbers with the last
kernel if you wish, on Monday. Perhaps Carsten would be interested in
running his tests?
