Performance Improvements ------------------------ -Some performance improvements in measured packet throughput have been observed -in a number of CSIT |release| tests listed below. Relative improvements are -calculated against the test results in CSIT rls1701 report. VPP-16.09 and -VPP-17.01 numbers are provided for reference. +Substantial improvements in measured packet throughput have been observed in a +number of CSIT |release| tests listed below, with relative increase of +double-digit percentage points. Relative improvements for this release are +calculated against the test results listed in CSIT |release-1| report. The +comparison is calculated between the mean values based on collected and +archived test results' samples for involved VPP releases. Standard deviation +has been also listed for CSIT |release|.
