[Haskell-cafe] Preferred way to get data from a socket

[Chad Scherrer]

Ok, cool. FWIW, the current documentation for Network says:

"For really fast I/O, it might be worth looking at the hGetBuf and
hPutBuf family of functions in System.IO."

But this looked pretty low-level to me, and I figured it might be outdated.

I also know Bulat Ziganshin had put together a nice-looking Streams
library (http://unix.freshmeat.net/projects/streams/) based on John
Goerzen's previous HVIO work, but I wasn't sure if the ByteString
stuff matches the speed and encapsulates all of the functionality of
that anyway. Or can/should they be used together somehow?
