Can't you tune this with sysctl?

  You can set net.core.wmem_default, though that's a system-wide setting you have to override. And then you can end up with large message queues instead, if you have a lot of small messages (which is a concern in the embedded systems I work on). The problem is really the large overhead of the messages, of close to a kilobyte per message. TCP sockets have just a fraction of the overhead.
