[ovs-dev] [PATCH 2/2] ofproto-dpif: Rate limit calls to facet_learn().

2013-03-26 Thread Ethan Jackson
In the TCP_CRR benchmark, ovs-vswitchd spends so much time in update_stats() that it has a significant impact on flow setup performance. Further work is needed in this area, but for now, simply rate limiting facet_learn() has a roughly 10% improvement with complex flow tables. Signed-off-by: Etha
