```
ps aux | grep dockerd
```
  Note the Docker PID.
2. Check system load:
```
top
```
  Exit using q.
3. Stop the dockerd process:
```
sudo -i kill -SIGSTOP <dockerd_PID>
```
4. Check the load to see if there is a change:
```
top
```
  Notice it indicates there is one stopped process. Exit using q.
5. Restart the Docker daemon:
```
sudo kill -i -SIGCONT <dockerd_PID>
```
Challenge

Check the Current Process Priority of the dockerd Process and if It Is Not 10, Set It to 10
1. Get the current priority (niceness):
```
ps axo ni,pid,comm | grep dockerd
```
2. Set the Docker niceness to +10:
```
sudo -i renice -n 10 <dockerd_PID>
```
3. Verify the change:
```
ps axo ni,pid,comm | grep dockerd
```
