stream results for $199 computer seem rather high...

John,

I have just put together one of the cheapest 64-bit Linux boxes: a $199
Emachines T3506 (3.2 GHz Intel Celeron D, 512BK cache, 512 MB RAM running
64-bit Fedora Core 5) and it seems to be getting rather high stream numbers.
  Could this be a new Mflops/$ high score? (I used gcc v. 4.1.1, -O6
-funroll-all-loops).

Increase the size of the arrays if this shows that
you are not getting at least 20 clock ticks per test.
