This way the frequency is read from sysfs only once per update cycle instead of every time the UI is redrawn. This also changes the code to read from /proc/cpuinfo instead. This is because reading from scaling_cur_freq stalls for 10ms if the previous read for the file was more than one second ago. [1] Since htop's update cycle is longer than that, it would cause the read of each CPU's scaling_cur_freq file to block the UI for 20ms. This easily led to a noticeable half-second lag on a 20+ CPU machine. /proc/cpuinfo also has a 10ms delay, but this applies for the whole file so the delay does not scale with the number of CPUs.
