Hello, Currently I'm integrating OVS head with DPDK 2.1. Based on my tests performance in all scenarios (confirmed on Phy2Phy and Vhostuser) has dropped about 10%. Please find example results below:
PHY2PHY (Bidirectional) DPDK 2.1: Iteration 1: 14,164,987 pps Iteration 2: 13,866,386 pps Iteration 3: 14,093,153 pps DPDK 2.0: Iteration 1: 15,406,646 pps Iteration 2: 15,410,182 pps Iteration 3: 15,404,678 pps VHOSTUser: DPDK 2.1: Iteration 1: 3,328,678 pps Iteration 2: 3,367,130 pps Iteration 3: 3,259,899 pps DPDK 2.0: Iteration 1: 3,786,969 pps Iteration 2: 3,736,117 pps Iteration 3: 3,557,150 pps Based on my test last commit where performance was the same was: 37f9a7270e800df5c603b2c76c73ed3bca3328d9 Bad commit: 1d493a49490fa90e09689d49280cff0d51d0193e You can find diff in attachment. Change is still compatible in OVS because in rte_pktmbuf_pool_init, NULL is passed as second argument. Did anyone noticed such performance drop? Could anyone give me some information why this implementation has changed? Any hints how to get back to previous performance would be very appreciated.
