Bug ID: 41379
           Summary: Terrible performance hit for small messages
           Product: Wine
           Version: unspecified
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winsock
          Assignee: [e-mail]

      Distribution: ---

I have a simple server and client that both run under Windows and Linux.
I am reading small messages (1-byte) in the client that are sent from the
server. The client is run under Wine, Linux, and Windows. The client is
compiled under Linux with g++ and under Windows with Visual Studio 2010. The
client that is run under Wine is about 20 times slower than the client running
under Linux or Windows. Could Wine be linking to the wrong version of the
system function recv? Turning off the Nagel algorithm with setsockopt makes no
difference.
