Hi, We see 40% traffic drop with UDP traffic over VxLAN and 20% traffic drop with UDP traffic over MPLSoGRE between OVS 2.8.2 & OVS 2.12.1.
We narrowed the drop in performance in our test is due to below commit and backing out the commit fixed the performance drop problem. The commit of concern is : https://github.com/openvswitch/ovs/commit/967bb5c5cd9070112138d74a2f4394c50ae48420 commit 967bb5c5cd9070112138d74a2f4394c50ae48420 Author: Darrell Ball <dlu...@gmail.com<mailto:dlu...@gmail.com>> Date: Thu May 9 08:15:07 2019 -0700 conntrack: Add rcu support. We suspect 'ct->ct_lock' lock taken to do 'conn_update_state' and for conn_key_lookup could be causing the issue. Anyone noticed the issue and any pointers on fix? We could not get any obvious commit that could solve the issue. Any guidance in solving this issue helps?
