# this one actually changes the CPU idle time and bossts performance somehow. you can see the change in the output of "cpupower frequency-info".
cpupower idle-set --disable-by-latency 0
# however it raises the temprature of the server and electricity consumption of the machine. You can enable idle mechanisms by below:
cpupower idle-set -E
