- the pinger distribution is much sharper (max frequency 987 vs 408 for raspberry-pi)
- there is a slight hint of multi-modaility in the pinger distribution less visible in the raspberry-pi distribution
- the minimum and maximum outliers are about a factor 100 lower for pinger than the raspberry-pi (~ +-0.1 vs ~10ms)
- the IPDV's are similar (0.017ms), whereas the standard deviations differ by almost a factor of 10 (0.021ms vs. 0.227ms. This further illustrates the impact of smaller outliers seen by pinger.
Comparing the IPD frequency distributions for the pinger.SLAC and pinger-raspberry MAs to their localhosts with those to TRIUMF it is seen that the differences are washed out as one goes to the longer RTTs.
Though there are large relative differences in the distributions, the absolute differences of the aggregated statistics (medians, IQRs) are sub millisecond and so should not noticeably affect PingER wide area network results.
