I noticed something about ByteStream performance that I don't
understand.
I have a test text document:
$ ls -sh test-text-file
956K test-text-file
Running this program, using the Prelude's IO functions:
module Main where
main = do

Hello,
Did you compile with -O2 ? That makes a huge difference when using ByteString.

Ah, that was exactly it. I feel silly.
module Main where
import qualified Data.ByteString.Char8 as B
main = do
content - B.readFile test-text-file

Hmm, I think we can do better than that. It would be nicer to have it
work fast without needing any -O flags at all in the user's module.
Lets look at
