Yes, on a machine with that speed, it will be several hours.

Buildworld always takes about the same time. The installworld on my 
machine runs <4 minutes.  Running mergemaster the first time on an 
upgrade can take a while. You need to look at /usr/src/UPDATING for 
when you need to run it and the options. 

The installs are always fast and only the builds take much time.

That you have done a full src-all on your cvsup. There are also some 
options that help in your /etc/make.conf. From what I saw a little 
while ago, the default make.conf is now in the examples directory. 

Don't let mergemaster replace your hosts entries and your user entries 
in master.passwd and groups. I edit the password entries manually with 
vipw and groups with vi. If you have a special /etc/printcap, it will 
try to replace it. Just pay attention is all that is required. You can 
save trouble if you back up /etc before you do the installs.
