Hi, I was studing how to use perf, when: [root@localhost Profiling]# perf record -r 10000 ./netlibtest Could not set realtime priority. ./netlibtest: Terminated [root@localhost Profiling]# perf --version perf version 3.9.0-301.fc19.x86_64
kernel-utils hasn't been a package in ages, and hopefully, this works fine in the latest fedora kernels.
