Some "manual copy & paste" data from the past (original post

As you can see, 5 hours was a possible value on a single-core
single-threat slow-as-ass CPU. But then the system became more
advanced, and 7 - 9 hours compile time became possible. :-)

Sadly I don't have a "copy" of my build time on my current
home PC, including a Core 2 Duo 4600 with 1.8 GHz and 2 GB RAM,
using a SATA disk, with FreeBSD 8-STABLE, but I think it was
around 5 hours for everything (including a custom kernel).
It would be nice if the build system would automatically issue
a log file or at least log message about build time and usage
statistics. If it wouldn't tell about my brain's age, I would
politely ask to have a "flower box"... ;-)
