[Haskell-cafe] Streaming bytes and performance

of course the program measures I/O performance. It just doesn't measure
the speed of the disk.

Anyway, a highly optimized benchmark such as the one you posted is
eventually going to beat one that's not as highly optimized. I think
no-one disputes that fact.

I was merely trying to point out that a program which encodes its
evaluation order properly is going to be reasonably fast without any
further optimizations.

Take care,
Peter
