I've figured out what cause the performance increase. When dmesg gets flooded
with messages syslog use 100% cpu for a while. Performance increase during that
time. The same thing can be achieved by running while true;do true;done. I
guess it has something to do with the cpu's power states.
It would be nice to always have that boost. Using fthrottle_mode=0 didn't help.
