Re: [Cable] Speedboost dead after Comstock migration?

Since migration to ATPIA here, I still get SpeedBoost but it either occurs much less frequently or its effects occur over a much shorter time period.

Here's my latest speed test:



I won't tell you what speed profile I'm on but it should be ridiculously easy to guess.

My speed test graph normally shows a spike at the beginning but it appears for less than a second and is clearly not long enough to affect the overall average. This is very tight control, almost looks like shaping of some sort. (Is this done at the CMTS or is there more complex equipment that does this? It's not the modem, I wouldn't think it would have the power and it only tells the CMTS what speed profile it's set at via the speed profile file loaded in it.)

This wasn't the case at all when I was on 28/1 disaggregated. SpeedBoost almost always had a large effect. I can see this by my old results on speedtest.net for sure.

I'm not complaining given the huge problems lots of TSI customers have been facing for weeks now (knocks on wood feverishly) but it's interesting.

I suspect that they've tightened the speedboost parameters on Comstock, probably due to limited backhaul bandwidth which would affect all customers

Yes, that happened before Comstock migration, but around the former McNicoll POI area, at least, that doesn't occur anymore.

I think it's a local issue related to the congestion etc. There were lots of speed and capacity problems on Dupont when it was created from Bloor and Etob as them moved the cabling. And they undersized the backhauls. Now it may be that they've chosen to limit the TPIAs who offer higher bandwidth more than their own customers.

But they certainly haven't disabled speedboost in other parts of the rogers footprint.

I get the same results constantly, even at 9:30 p.m. on weeknights and in the morning. So, I don't believe what I'm observing can be explained by local congestion. Perhaps you're referring to the general congestion issue that was affecting everyone previously?
