See the explanation below.
Explanation:
yum install httpd
systemct1 --now enable httpd
systemct1 status httpd
netstat -tunlp | grep 80
pkill <processname>
systemct1 restart httpd
systemct1 status httpd

The /etc directory contains configuration files for system-wide settings and services in Linux. Files like /etc
/fstab, /etc/hosts, and /etc/passwd reside here, controlling various aspects of system behavior and service configurations.

Explanation
The slowness is caused by the CPU being overloaded. The iostat command shows that the CPU utilization is
100%, which means that there are more processes competing for CPU time than the CPU can handle. The other options are incorrect because:
The system is not running out of swap space, as shown by the iostat command, which shows that there is no swap activity (si and so columns are zero).
The memory is not exhausted, as shown by the free -m command, which shows that there is still available memory (avail column) and free buffer/cache memory (buff/cache column).
The processes are not paging, as shown by the vmstat command, which shows that there are no major page faults (majflt column) and no swap activity (si and so columns). References: CompTIA Linux+ Study Guide, Fourth Edition, page 417-419, 424-425.

After fixing issues in the code, the next step is to merge these changes into the main branch. This is typically done by creating a pull request78.
