Subject: TCP_STREAM performance regression on commit b3613118
Date: Fri, 17 Feb 2012 16:18:14 +0800	[thread overview]
Message-ID: <1329466694.12669.2976.camel@debian> (raw)

The tcp_stream loop back performance has about 10% drop on the
commitment on our core2 2 sockets server. This commit has 2
parents(7505afe28, 5983fe), but both of them have no regression. So
guess the impact just happened when this 2 parents joint. That beyond
our capability to dig it more.

Any ideas? 

Regards! 
Alex
