From 66e1e3b20cbbf99da63e6c1af0fc6d39c2ed099a Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Wed, 13 Jun 2007 01:03:53 -0700 Subject: [TCP]: Set initial_ssthresh default to zero in Cubic and BIC. Because of the current default of 100, Cubic and BIC perform very poorly compared to standard Reno. In the worst case, this change makes Cubic and BIC as aggressive as Reno. So this change should be very safe. Signed-off-by: David S.
