STM after 9pm

It is a pity that VM don't show the same kind of openness that Comcast have recently:

Today, Comcast has approximately 3300 CMTSes deployed throughout our network, serving our 14.4 million HSI subscribers.

Each CMTS has multiple “ports” that handle traffic coming into and leaving the CMTS.

In particular, each cable modem deployed on the Comcast HSI network is connected to the CMTS through the ports on the CMTS. These ports can be either “downstream” ports or “upstream” ports, depending on whether they send information to cable modems (downstream) or receive information from cable modems (upstream) attached to the port.

Today, on average, about 275 cable modems share the same downstream port and about 100 cable modems share the same upstream port.

OK So it's a nerdy interest but would be interesting to see VM's numbers. You can get contention ratios from this stuff.

38Mbit / 275 subs = 138.2kbit/s downstream each and 12.9 / 100 = 129kbit/s upstream each. Upstream figure is a guesstimate but should be about right considering Comcast have deployed a fair bit of DOCSIS 2 upstream action at 3.2MHz / 64QAM.

Based around a standard tier of 6Mbit down and 2Mbit up gives contention of 44:1 downstream and 15.5:1 upstream

That doesnt seem that good

If someone can remember the Virgin Media customer split between M / L and XL you can also guesstimate it on VM. I reckon in a fully L upgraded area the average speed as sold would be 6.2Mbit down and 384k up. Assuming that you'd be looking at 44.86:1 downstream on VM and 4.36:1 upstream, we assume 275 subscribers on a 38Mbit downstream and 100 subscribers on an 8.8Mbit upstream who are split roughly 60 / 30 / 10 between M / L / XL.

EDIT: I should mention that the upstream bit isn't always going to be the case, I know that in a lot of instances Virgin are only running 4.4Mbit upstreams, and I have serious doubts that Virgin's network has so few customers per downstream.

I used to think over-subscription was the problem, but since I switched to Giganews, my dl is 20mb without fail, then when i hit STM it's 5mb without fail.

I also have similar problems to this , i've been using DU meter to monitor my connection for the past month or so and even tho i've only used a total of 1.3gb over a 7 day period im still being managed down to 5mb once 4pm arrives,every week without fail.I've taken this up with virgin many times all to no avail , the only response i can seem to get is that my router is to blame, yet i can get my full 20mb before 4pm with the router in the loop.
