From cb95ea32a457871f72752164de8d94fa20f4703c Mon Sep 17 00:00:00 2001 From: Vlad Yasevich Date: Fri, 4 Sep 2009 18:20:59 -0400 Subject: sctp: Don't do NAGLE delay on large writes that were fragmented small SCTP will delay the last part of a large write due to NAGLE, if that part is smaller then MTU. Since we are doing large writes, we might as well send the last portion now instead of waiting untill the next large write happens. The small portion will be sent as is regardless, so it's better to not delay it. This is a result of much discussions with Wei Yongjun and Doug Graham . Many thanks go out to them.
