What we are comparing here (Solaris vs Redhat Linux) is doing a full bootstrap
of C and Ada, and this seems to take reasonably comparable times on the
two machines (the Sun is slower by a factor of 2-3, but it is also a slower
machine by this factor).
What about "make check", do you see the same matching ratio?
I really doubt you will.... the Linux box should nuke the Solaris
one in terms of how long it takes to run "make check" even just
for the C language.
Linux also nukes Solaris in terms of how long it takes to build
libjava, but that is mostly a bug in the java compiler which Mark is
fixing (during compilation the java compiler calls stat() on the same
file a couple thounsand times, something like this).
But, again, "make check" is the real killer under Solaris.
