A high load average should have your CPUs running near 100%; if they
are not, on some platforms that tends to indicate that many processes
are (or would be) runnable but are being blocked in a short-term wait
condition due to network or disk I/O, or are being affected by VM
paging activity. This line of your top output indicates many
processes are in a WAIT condition:
