4 Changes in |csit-release|
5 -------------------------
7 #. **VPP performance tests**
9 - *MRR tests* - New Maximum Receive Rate tests measure the packet
10 forwarding rate under the maximum load offered by traffic
11 generator over a set trial duration, regardless of packet loss.
12 MRR tests are used for continuous performance trending and for
13 comparison between releases.
15 - *Service Chaining with SRv6* - New SRv6 (Segment Routing IPv6) proxy
16 tests measure performance of SRv6 Endpoint fronting SR-unaware
17 appliance via masquerading (End.AM), dynamic proxy (End.AD) or
18 static proxy (End.AS) SR functions.
20 #. **Presentation and Analytics Layer**
22 - *Performance trending* - Added continuous performance trending and
23 analysis. New Performance Trending and Performance Analysis jobs
24 executed regular throughput tests, with results being subsequently
25 analysed and trend and anomalies summarized and presented in VPP
26 Performance Dashboard and trendline graphs.
28 #. **Test Framework Optimizations**
30 - *Performance tests efficiency* - Qemu build/install optimizations,
31 warmup phase handling, vpp restart handling. Resulted in improved
32 stability and reduced total execution time by 30% for single pkt
35 - *General code housekeeping* - ongoing RF keywords optimizations,
36 removal of redundant RF keywords.
41 Relative performance changes in measured packet throughput in |csit-release|
42 are calculated against the results from |csit-release-1|
43 report. Listed mean and standard deviation values are computed based on
44 a series of the same tests executed against respective VPP releases to
45 verify test results repeatability, with percentage change calculated for
46 mean values. Note that the standard deviation is quite high for a small
47 number of packet throughput tests, what indicates poor test results
48 repeatability and makes the relative change of mean throughput value not
49 fully representative for these tests. The root causes behind poor
50 results repeatability vary between the test cases.
55 NDR throughput changes between releases are available in a
56 CSV and pretty ASCII formats:
