[mpich-discuss] Very long configuration time

[Kenneth Raffenetti]

The Intel compilers could also be a source of slowdown. Are they 
installed on a network filesystem? They may also call out to a network 
license server each time they are invoked for a compile test. Does just 
compiling a small program take a long time with icc, ifort, etc.?
