From 2da18b6724b7daf7c3a973515fc3d59e7d2c4622 Mon Sep 17 00:00:00 2001 From: Rajesh Amaravathi Date: Wed, 22 Feb 2012 14:51:53 +0530 Subject: transport/socket: configuring tcp window-size Till now, send and recieve buffer window sizes for sockets were set to a default glusterfs-specific value. Linux's default window sizes have been found to be better w.r.t performance, and hence, no more setting it to any default value. However, if one wishes, there's the new configuration option: network.tcp-window-size which takes a size value (int or human readable) and will set the window size of sockets for both clients and servers. Nfs clients will also be updated with the same.
