Well, Sun has some experience in computing, too :-)
Also, IIRC, GCC does not do any architecture optimisation by default, it builds
for 386 or 486, while the -fast option on the Sun CC compiler does.
"Note that -fast on x86 expands to -xarch=native"

GCC could probably get more performance with some tweaking, too. -fast seems to
be a handy shortcut.

You don't have to buy it -- you can try it before :-)
Then, it's up to you to decide whether it work better for your particular
application, and if it's worth the price.
