Re: [ovs-discuss] Poor GRE performance - maybe due to using ip_gre kernel module ?

Indeed, I managed to get very good results after I disabled TSO on the gre_sys interface. As a curiosity, disabling all 3 (TSO, GSO and GRO) on gre_sys interface returned good performance but half the best performance (obtained when only TSO is off). FYI: LRO was off by default for me. Thanks

Hi, The TL;DR is that in Ubuntu 16.04 the base openvswitch-switch package knows nothing about dpdk. But the openvswitch-switch-dpdk package does. please follow the whole page around https://help.ubuntu.com/16.04/serverguide/DPDK.html#dpdk-openvswitch for some guidance. Christian Ehrhardt

Yepp, Ben has right. There are a bunch of performance analyses on the Internet that presents the throughput of software based switches, like OVS, using multiple cores. If your traffic is really simple (like a packet generator's simple pattern, i.e., when all header information are the same for
