The following is my general finding so far:

Special features of Pentium 4 cpu is not generally utilized
by gcc-2.95.** which is used for most Linux distributions rpms.
Latexing a big document with Zeon Pentium 4 at 1.7GHz (52 sec) is actually
even slower than Pentium III running at 700MHz giving 35 sec.

On Athlon at 1.6GHz, it gives 16 sec.  The best.

Is my understanding for the reason of slow speed with P4 correct?
gcc-2.95.  If I do obtain te-latex.src.rpm and then compile it
with gcc-3.1, would I get much faster binary under Pentium 4?

The problem with Pentium 4 is not just limited with Latex.
I in fact hate Pentium 4, because I simply believed in
their high SPEC rating, and bought a bunch of Pentium 4 Xeon
duals only to find out that the even the Fortran speed
(with their Intel compiler) is in fact dismal.

Regards,

Hugh
