Can we see Improvement in IPV6 perfSONAR traffic for the RAL-LCG2 Tier1 site?

In three words (or my TL;DR response would be,) Yes and No.
You may remember I made an analysis of the perfSONAR rates for both IPv4 and IPV6 traffic from the WLCG Tier1 at Rutherford Appleton Laboratory to other WLCG sites. Here is a quick update for new measurements is a plot showing current perfSONAR rates for sites from 8 months ago, their new results, and values for new sites which have been IPV6 enabled and included in official WLCG mesh testing.

IPv4 vs IPv6perfSONAR throughput rates between RAL and other WLCG sites.

What I find interesting is that we still have some sites which have vastly better IPv4 rates rather than IPv6. NB we have 16 sites still with data, 5 sites with no current results and 10 new sites which have been added since the last tranche of measurements.
