What does cat Proc Loadavg mean?
This file provides a look at the load average in regard to both the CPU and IO over time, as well as additional data used by uptime and other commands.
How do you interpret load average?
If the 1 minute average is higher than the 5 or 15 minute averages, then load is increasing. If the 1 minute average is lower than the 5 or 15 minute averages, then load is decreasing. If they are higher than your CPU count, then you might have a performance problem (it depends).
What is a good load average?
The general rule of thumb is that the load average shouldn’t exceed the number of processors in the machine. If the number of processors is four, the load should generally stay under 4.0.
What does Htop load average mean?
The load average represents the average system load over a period of time. 1.0 on a single core cpu represents 100% utilization. Note that loads can exceed 1.0 this just means that processes have to wait longer for the cpu.
What is the difference between CPU load and CPU utilization?
The first thing to understand is that CPU load is not the same thing as CPU usage. Even though they might sound similar, they’re quite different. CPU usage is a measurement, in a percentage, of how much time the CPU spends actively computing something.

What is normal CPU load?
How Much CPU Usage is Normal? Normal CPU usage is 2-4% at idle, 10% to 30% when playing less demanding games, up to 70% for more demanding ones, and up to 100% for rendering work. When watching YouTube it should be around 5% up to 15% (total), depending on your CPU, browser and video quality.
What is the difference between load average and CPU usage?
Basically, load average is the amount of traffic to your CPU(s) over the past 1, 5, and 15 minutes. Generally you want this number to be below the number of CPU(s)/cores you have. 1.0 on a single core machine means it’s using the CPU to it’s maximum, and anything above that means things are getting queued.
How do you read htop output?
Understanding CPU Usage in htop
- Blue: Display percentage of CPU used by low priority processes. (
- Green: Displays percentage of CPU used for processes owned by normal users.
- Red: Displays percentage of CPU used by system processes.
- Orange: Displays percentage of CPU used by IRQ time.
What does R and S mean in htop?
R – running or runnable (on run queue) S – interruptible sleep (waiting for an event to complete) D – uninterruptible sleep (usually IO)
What is CPU load?
CPU load is the number of processes which are being executed by CPU or waiting to be executed by CPU. So CPU load average is the average number of processes being or waiting executed over past 1, 5 and 15 minutes.
