A system administrator is using htop to monitor a Linux server and notices that a non-critical data analysis process is consuming a high amount of CPU. This is negatively impacting the performance of a critical web application running on the same server. To mitigate this, the administrator decides to lower the priority of the data analysis process. After selecting the process in the htop interface, which key should be pressed to decrease its priority (increase its nice value)?
The correct key to decrease a process's priority in htop is F8. Decreasing priority is achieved by increasing the 'nice' value, making the process 'nicer' to other processes by yielding CPU time. The F7 key increases the priority by decreasing the nice value. The F6 key is used for sorting the process list. The r key is used to change the priority (renice) in the standard top command, not in htop.
