you can make permanent making blacklisted on boot:

sudo echo "blacklist intel_powerclamp" > /etc/modprobe.d/disable-powerclamp.conf

however should noted powerclamp feature there prevent processor further overheating limiting how of cpu can used. in fact processes (1 each cpu core) aren't using cpu, rather dictating how of should not used.
why things slower.

instead of disabling feature, suggest make sure fan working , inside of computer , vents clean , not blocked dust etc. feature comes on when machine overheating, try prevent overheating further. in fact disabling cause machine overheat , hardware damaged.

so highly advise make sure fan working , machine isn't overheating before deciding turn feature off.
