It is totally a function of your computer. Since, you didn't provide 
that information, we can only provide information on our personal 

I follow current, since I don't think 5.x is up to 4.x release quality 
at this point. I don't think it is far off, just not quite there. A 
buildworld, which is the longest part of an upgrade, requires 50+ 
minutes on my AMD 1600+ with 512 MB of DDR-266 memory and 3 ATA-100 
HDs. Having less memory won't affect the build time unless you produce 
swaping. Having both /usr/src and /usr/obj on the same HD will also 
increase compile times.

The buildkernel probably takes on the order of 10 minutes since it is 
long enough that I won't sit there to watch and I haven't timed my 
build script. The installs probably take less than 5 minutes.
