The existing NFS setup which work by pair of machines in the same datacenter: gcc11/12, gcc13/14, gcc16/17 is currently unused according to the munin statistics: http://gcc12.fsffrance.org/munin/fsffrance.org/comparison-day.html#Nfs This setup uses local gigabit so NFS is nearly transparent and when I set it up I tested a NFS build and it had the same performance as a local build. As mentionned in: http://gcc.gnu.org/wiki/CompileFarm "/n/NN points to gccNN:/home either by NFS or via symlinks within a datacenter, so please use /n/NN/USER/... for PATH and prefix, eg {{{/n/12/guerby/my-install} so that your build will work from most machines" If you avoid /home/USER in configure and use /n/NN/USER instead the existing setup already allows you to switch easily and transparently between two machines. Plus all the extra are installed uniformly in /opt/cfarm/xxx on all farm machines. So if your machine is loaded please use: http://gcc12.fsffrance.org/munin/fsffrance.org/comparison-day.html#System to check if the other one of the pair is in better shape and switch machines right away :). If these already existing pair NFS mounts prove not enough I could setup pairwise NFS over openvpn between datacenters but I would have to ask permission from our hosts.
