Resulted in improved - stability and reduced total execution time by 30% for single pkt - size e.g. 64B/78B. +#. TEST FRAMEWORK OPTIMIZATIONS - - *General code housekeeping* - ongoing RF keywords optimizations, + - **General Code Housekeeping**: Ongoing RF keywords optimizations, removal of redundant RF keywords. -Performance Changes -------------------- - -Relative performance changes in measured packet throughput in |csit-release| -are calculated against the results from |csit-release-1| -report. Listed mean and standard deviation values are computed based on -a series of the same tests executed against respective VPP releases to -verify test results repeatability, with percentage change calculated for -mean values. Note that the standard deviation is quite high for a small -number of packet throughput tests, what indicates poor test results -repeatability and makes the relative change of mean throughput value not -fully representative for these tests. The root causes behind poor -results repeatability vary between the test cases. - -NDR Changes -~~~~~~~~~~~ - -NDR throughput changes between releases are available in a -CSV and pretty ASCII formats: -
