Why does htop have three load averages?
On htop, it shows three load averages, one bold, one normal, one red. What do they signify?
The first one is a 1 minute load average, second is 5 minutes, third is 15 minutes, just like the uptime command. They do not have any special correlation in htop other than to stand out from each other.
