36 Performance Improvements
\r
37 ------------------------
\r
39 Substantial improvements in measured packet throughput have been observed in a
\r
40 number of CSIT |release| tests listed below, with relative increase of
\r
41 double-digit percentage points. Relative improvements for this release are
\r
42 calculated against the test results listed in CSIT |release-1| report. The
\r
43 comparison is calculated between the mean values based on collected and
\r
44 archived test results' samples for involved VPP releases. Standard deviation
\r
45 has been also listed for CSIT |release|. Performance numbers since release
\r
46 VPP-16.09 are provided for reference.
