Yes, it does strongly depend on the network speed; less than switched
100Mbps is marginal.

The other important thing is the characteristics of the makefile or
build system; if it can't parallelize well it limits the possible

Cygwin is pretty slow for some operations commonly used in Makefiles,
that may be the limiting factor here.
