I'm not sure exactly what you mean. What performance issues? The big story is the difference in the ranking of the plugs compared to the Smallnetbuilder Roundup. A complete reversal for the Netgear - it aced it every place, every time in my tests.
In the UK, yes we use 230V ring mains. But we do use 2.5mm2 mains cable, and I can't remember the last time I saw a property without a circuit breaker unit.
I did get slightly lower best-case results compared to SNB even at 490Mbps+ link rates on the same double socket. If due to voltage and device operation, then yes it will be a universal US/UK thing. If due to my local mains condition, then not so.
I also captured a much greater range of performance than the SNB roundup, by doing a whole house survey: 40Mbps application throughput minimum by SNB is a big overestimation. You have just found that out for yourself I think.
On the rather large long-term day-to-day variability, SNB has not done any explicit longitudinal tests. However, it has in effect performed some: look at the Netgear results from its standalone review on one day, then look at its results from the Roundup on another day. And do the same for the Trendnet. You can draw your own conclusion! (I can tell you now, I recorded all the firmwares before and after updates, and my shootout blows any theories of firmware being responsible out of the water).
