Jay Kreps commented on KAFKA-200:
---------------------------------
Interesting. Can we validate the setting directly by checking
getReceiveBufferSize()?
I think the reason it may be working is that linux defaults tcp window scaling
on...I think the current approach would not work on Solaris because it defaults
tcp window scaling off. Or maybe I am wrong. But I think we would be better off
doing it the way they recommend and setting the buffer size in the way the
documentation encourages.

>
> * Make the send / receive socket buffer size configurable in server.
> * KafkaConfig.scala already has the following existing variables to support
> send / receive buffer:
> socketSendBuffer
> socketReceiveBuffer
> * The patch attached to this ticket will read the following existing settings
> in <kafka>/config/server.properties and set the corresponding socket buffers
> . . .
> # The send buffer (SO_SNDBUF) used by the socket server
> socket.send.buffer=1048576
> # The receive buffer (SO_RCVBUF) used by the socket server
> socket.receive.buffer=1048576
