Hello anyone
I've written a snippet which generates a file full of random strings.
When compiled with -O2 on ghc-7.6, the generation speed is about 2Mb per
second which is on par with interpreted php. That's the fact I find
rather disappointing. Maybe I've missed something trivial? Any
System.Random is very slow. Try the mwc-random package from Hackage.

What about this? I've tested on my pc and seems pretty fast. The trick is
to generate the gen only once. Not sure if the inlines helps, though:
import qualified Data.Text as T
import System.Random.MWC
import Control.Monad
import System.IO
import Data.ByteString as B
import Data.Word (Word8)
