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 repeatibility, 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.
