Hi, I just found the 680k tps TCP_CRR test result in the nsdi2015
paper "The design and implementation of Open vSwitch" [1]. Hmm, the
120k tps in section "Cache layer performance" is similar to what I
have got. But how were they boosted to 688k for both Linux bridge and
Open vSwitch in section "Comparison to in-kernel switch"?
