The cause is Gerrit 26456, unpinning random seed, needed to make TRex workers
generate different sequences of packets. [CSIT-1731]
- [5] OPEN Progression in performance of tests running VPP (l2xc) inside VM.
- Due to relatively high stdev of results, bisecting has not found a cause yet.
+ [5] DONE Progression in performance of tests running VPP (l2xc) inside VM.
+ Consequence of a fix making worker placement deterministic, Gerrit 25309.

[7] POSTPONED Possible anomaly, but stdev of results is high.
Currently, the performance differences are considered to probably be just noise.
- [8] OPEN Regressions in some tests with VPP in VM and using l2xcbase as vswitch.
- The results have surprisingly small stdev, more investigation needed.
+ [8] DONE Regressions in some tests with VPP in VM.
+ Tests using l2xcbase as vswitch have small enough stdev for bisect.
+ The switch to clang-9 compiler, Gerrit 26744, has been identified as the cause.

[9] OPEN Progression in ip6 scale tests. Multiple candidate changes may have
[12] OPEN Progression in some l2bdscale tests. [CSIT-1745]
[13] DONE Stateless ACL test have the same performance in 2005.0-4 as in
- 2001.0-2, the difference shown here is just a consequence of API change
- having a performance impact when VPP version does not match CSIT version.
+ 2001.0-2. The difference shown here is inflated by an API change, see [1].

- [14] DONE Statefull ACL test have better performance in 2005.0-4 as in
- 2001.0-2, but the difference shown here is inflated due to API change
- having a performance impact when VPP version does not match CSIT version.
+ [14] DONE Stateful ACL test have better performance in 2005.0-4 as in
+ 2001.0-2. The VPP part of API change, Gerrit 26184, made VPP faster.
+ The difference shown here is further inflated by the API change, see [1].
