A server is experiencing intermittent slowdowns. The administrator runs `vmstat 1 10` and observes the following pattern: the `r` (runnable processes) column is consistently above 10, the `us` (user CPU) column is around 80%, and the `wa` (I/O wait) column is near 0. The `si` and `so` columns are 0. The load average is 12.5. What is the most likely cause of the slowdown?

The system is I/O-bound, with processes waiting for disk access.

The system is CPU-bound, with more runnable processes than available CPU cores.

The system is memory-bound, with processes swapping to disk.

The system is experiencing network congestion, causing processes to wait for network I/O.

A developer starts a long-running compilation job in the foreground of a terminal session. The developer realizes the job will take too long and wants to continue using the terminal for other commands. The job is currently running in the foreground. What should the developer do?

Open a new terminal session and run the compilation there, leaving the current one running.

Press Ctrl+C to stop the job, then restart it with `&` at the end of the command.

Press Ctrl+Z to suspend the job, then run `bg` to continue it in the background.

Run `bg` directly without suspending the job first.
