Switched over to AAISP this afternoon.
Luurrverly.
Inbound real TCP payload throughput is much healthier this afternoon at well over 1.9kb/s (typically 1.96Mb/s say) and this is during peak hours, and that's near enough up to the limit imposed by the current BTW IP Profile 'rung' of 2000 currently in effect, especially remembering that I presumably need to also allow for TCP's overheads to be deducted from that figure of 2000. Latency / ping times to the nearest hop are down to 45ms (-ish) which I would think is about where they should be for a line with interleave.
Comparing these numbers with Demon, from spot measurements at various times during the last two week, real-world TCP inbound throughput ranged from 1.53Mb/s at midday on one day, to 1.71Mb/s on another day, again at midday and only up to 1.87Mb/s very late at night. The ping-to-nearest-hop times were consistently worse with Demon, more often than not from 65ms or above rather than in the 40s, and at times they had been as high as 100ms and last Autumn even more like 150ms at one point.
Not that its anything to do with AAISP or Demon, but the faithful Netgear DG834v3 (with various h/w pamperings) was purring away at a sync rate of 2464 with 5.5-6dB SNR margin and the usual 62dB attn. So well above the sync rate for IP profile 2000 but not close to that for 2500 unfortunately.
Concerning the accuracy of these TCP test figures, I also think there is a likelihood that there is a danger that these figures are on the low side as I used PlusNet's Flash-based speed tester (among others) all of which are outside the AAISP's network so congestion could play a factor. I should have used the BT Wholesale speed test for a more accurate result, but the BTW tool now wants strange magic runes of power to be entered into it before you can use it, and these I don't have at hand. I have compared several of the popular UK-based test servers against one another from time to time and find them broadly in agreement, so it doesn't seem that the PlusNet one is especially stressed or congested though.
AAISP - a really, really good start - good first impression anyway.
