13 Your laptop isn't sending its compilation jobs to your desktop. Have you
14 used gkrellm or similar to check for network traffic?
16 I think I'd take a different approach, one that I dare say you can
17 anticipate. By all means take the advice you're about to be offered to get
18 distcc working, but why not create a chroot on your desktop, NFS export the
19 packages directory from the laptop to it and do the whole job there? Then
20 return to the laptop and emerge -k. It does need more keystrokes but it uses
21 far less CPU. You just need to copy /var/lib/portage/world, make.conf and
22 the /etc/portage tree to the chroot before you start.
24 I did once get distcc working, but as Neil has observed re Atoms, a lot of
25 work is still done before compilation is farmed out to the distcc server,
26 rather diluting the benefit of distributed compilation.
