The following example shows how to estimate the system boot time of a sample
configuration consisting of 4 CPUs and 32 Gbytes of system memory, with 8 Gbytes
of memory on the most populated CPU.

Reference for Sample Outputs
At the default setting of verbosity = normal, POST and OpenBoot Diagnostics
generate less diagnostic output (about 2 pages) than was produced before the
OpenBoot PROM enhancements (over 10 pages). This section includes output
samples for verbosity settings at min and normal.
Note – The diag-level configuration variable also affects how much output the
system generates. The following samples were produced with diag-level set to
max, the default setting.
