Mate pravdu, nevedel som ju zistit.
Takze tu je:
  The sparc processor operates at 143 MHz,
        and has a sparc floating point processor.

Vsade bolo pouzite gcc
OPTION = -O2 -fomit-frame-pointer -fforce-addr -fforce-mem -ffast-math

Vsetky stroje boli v pokoji, okrem toho AlphaServeru, kde boli nejake
minimalne aktivity.

Pokusil som sa prekompilovat test s pouzitim cc. Volbu -fast nepoznal, tak
som mu nechal povodne volby. Vysledok je na konci mailu.
Ako som vsak zistil z cc -v
gcc version cygnus-2.3.3

gcc -v
gcc version 2.7.2.f.1

Za to cecko od SunSoftu je asi potrebne si priplatit. :(

Ano, teraz to uz viem, rozpadli sa moje iluzie o vykone SPARCov.
Pre zaujimavost, urobil som este jeden test, cisto len procesora.

	integer		floating point
gcc	1.870		1.494
cc	1.716		1.424

Index je porovnanie k vykonu pocitaca DELL s procesorom Pentium 90.
(U alphy sa tie indexi pohybovali okolo 6)
