To implement high-performance web servers, I would like to remove overhead of String and want to use ByteString instead
1. when dealing with files involve system call, overhead of converting String forth and back to ByteString would be probably small compared to syscall itself 2. in the Haskell maillists, there were huge discussions about filenames nature. on Windows, filename is actually a list of Unicode characters (usually passed to Win32 APIs in UTF16 encoding), on Linux it's byte string in some partition-specific encoding. all the details are dealt in the hard way by the standard libraries. running ahead of them may be very difficult job -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
