Kinda funny:

[clayne at build02-sol8-x86 /tmp]$ gcc -O3 -o fib fib.c
[clayne at build02-sol8-x86 /tmp]$ time -p ./fib 36
./fib: calculated 10 fibonacci(36) in 13.000000 seconds
real 13.72
user 13.68
sys 0.00
[clayne at build02-sol8-x86 /tmp]$ gcc -Os -o fib fib.c
[clayne at build02-sol8-x86 /tmp]$ time -p ./fib 36
./fib: calculated 10 fibonacci(36) in 12.000000 seconds
real 12.59
user 12.58
sys 0.02
[clayne at build02-sol8-x86 /tmp]$ gcc -Os -fomit-frame-pointer -o fib fib.c
[clayne at build02-sol8-x86 /tmp]$ time -p ./fib 36
./fib: calculated 10 fibonacci(36) in 10.000000 seconds
real 10.75
user 10.75

None of these tests mean much as CPU types are wildly different.
