A database server is experiencing performance degradation. The administrator runs `vmstat 1 5` and observes that the `si` and `so` columns show consistently non-zero values, while the `wa` column is near zero. The `free` memory column is decreasing over the sample period. What is the most likely cause of the performance issue?

The system is experiencing heavy CPU contention from the database processes.

The system is actively swapping memory pages to disk, causing disk I/O that slows down the database.

The system is performing normal paging activity that does not affect performance.

The system is out of disk space, causing the database to fail writing to its data files.

A system administrator runs the uptime command and sees the following output: 'load average: 2.50, 1.80, 1.20'. What do these three numbers represent?

The percentage of CPU utilization over the last 1, 5, and 15 minutes, respectively.

The total memory usage in megabytes over the last 1, 5, and 15 minutes, respectively.

The average number of processes in the run queue over the last 1, 5, and 15 minutes, respectively.

The number of running processes at the current moment, 5 minutes ago, and 15 minutes ago.
