Bernd Sieker has built a 1.5_BETAish snapshot on a 40 MHz 68040 Amiga, with
everything over NFS, with the exception of /tmp on MFS.

Server was a fast Pentium roman($N) NetBSD BOX, with heavy usage of softdep
for most, and LFS for the DESTDIR and RELEASEDIR.

Now to the benchmarks:

1.5 build:

My machine,	68060/50 MHz/112 MB,	local disk:	31 hours
Bernds machine,	68040/40 MHz/64 MB,	NFS:		60 hours

1.4.3 build, if I recall right:

he's machine,	68040/33 MHz/64 MB, local disk, 1.4 build: 28 hours
my machne, 	68060/50 MHz/112 MB, local disk, 1.4 build: 15 hours


68060/50 with local disk is about twice as fast as 68040/33 with local disk.
68060/50 with local disk is about twice as fast as 68040/40 with decent NFS=


68040/40 with decent NFS is about as fast as 68040/33 with local disk.

Thats not too bad, IMHO. Your mileage will vary when other people use the
network or the NFS server.
