Re: SHUB3 Puma Bug - TBB BQM Improvement
Yeah they never told me either, I just noticed I had access to the trial forum, then checked firmware version to see it had been updated.

Same, didn't notify me I was part of the trial. Not sure what I'm even supposed to be doing as they haven't said anything.

Same here, I went and looked as I can see the trial access forums part. No FW update nor no email from them.

If you can access the trials forum then you need to let them know you didn't get the firmware drop as a few missed out.

Re: SHUB3 Puma Bug - TBB BQM Improvement
Got the firmware then the next day everyone not on the trial seemed to be getting it anyway, so not sure what the point in the "trial" was....

Yes it was strange that a few days after the trial started most people seemed to get given it.

To placate people and paint a lovely TBB monitor.
IMHO the underlying chipset cannot be fixed by a firmware update.

Re: SHUB3 Puma Bug - TBB BQM Improvement
Here's what I posted in the VM Forum:
1/
The PUMA 6 CPU is of low spec (single core) and is thus heavily utilised because all of the traffic on a segment hits it and is filtered through by your own security key generated when the modem is switched on.
2/
The processor and associated memory is so overloaded that every 20 to 30 seconds it does an emergency interrupt to clear its cache and so on. This will stop some games in their tracks.
3/
Every second, the TBB BQM system, for those subscribing, makes an ICMP call (you can Google that) to your router. This call has to be handled hitherto by the Puma 6 chip.
4/
The yellow portion of the graph is very misleading. It is a maximum latency measure. So that in any 30 second period, you might get 25 of those ICMP pings being serviced in around 10 to 20 milliseconds; when the Puma 6 chip interrupts, the ping round trip time rises and it is this maximum that is recorded in the BQM as the yellow area. The blue average area remains relatively unpurturbed.
5/
The new firmware displaces processing of ICMP packets from the Puma 6 into the AR9382 chip. A clever dodge which shows a nice BQM graph, but isn't even the tip of the iceberg when it comes to load that remains on the Puma 6.

What are people saying about their gaming experience on the new firmware?

Re: SHUB3 Puma Bug - TBB BQM Improvement
Surprisingly little. They appear fixated on the BQM! At least that's my reading.
Anyway, a PRO comment is at post http://community.virginmedia.com/t5/...3653927#M40407
And a NAY comment: http://community.virginmedia.com/t5/...3650922#M40236
And that's about it. Rest is a sideshow (dozens of posts).

As I said, what they've fixed is useless because in the real world people don't do pings except to make false deductions on the state of their circuit/hub.

I hope they have a Hub4 modem in the pipeline that doesn't have this issue and i can get on a trial.
