I understand that PN apply QoS to a customers line for good reason too. I just don't know what this service is called but I'd like to request to have it taken off if that is possible. I understand PN have full control over this so I'd like to have it removed please.
My reason for this is simple I am a enthusiast and would like to manage this myself with my new router (RT-N56U).
Cheers guys.

However, if you still want to try your line unrestricted by QoS, you can override it by applying the 'Pro add-on' to your account.
The 'Pro add-on' was more relevant to legacy accounts that had various traffic restrictions, but if you are on the new 'Unlimited' account then you will probably not notice any improvement.

I find it hard to use the word restrictions and fast pace gaming in the same sentence unless I'm talking downloading large files without it being a bad thing.
I thought the pro add-on was to give priority to the main routers/switchers or gateways. I thought there was a QoS applied to individual connection's (end user) to make sure things like streaming, voip and gaming don't become affected by downloads. Not sure how that would work but that was the impression I got from a post a while back.
I dont think the pro add-on is quite what I'm trying to achieve. I dont want to add a rule. I want to remove the process to eliminate any delay and unnecessary processing of data, allowing for better flow of data.

I'm talking about something that will only affect my line only.

This is unbuffered, so if data arrives too quickly then random packets will get dropped and your computer will have to request resends.
The Plusnet profile should be very slightly lower than the BT profile and is the maximum rate at which Plusnet send data to your exchange.
This is buffered, so any data overruns here should be handled nicely and no data should be lost.
The Plusnet QoS, analyses all the packets being sent to your connection and tries to pack as much data as possible into the bandwidth that is available as determined by your Plusnet line profile. If that bandwidth becomes full, due to heavy traffic loading, then the QoS will drop or buffer the LOWEST priority traffic packets in such a way that your HIGHEST priority packets are not affected.
When you use the 'Pro Add-on' (i.e. switching off QoS), the effect on traffic prioritization is that all packets have equal priority.
This means the previously low priority packets now run at full speed all the time, but this has the effect that when your line is fully loaded, then both high and low priority packets will be dropped.
Therefore it is VITAL that your Plusnet line profile is set correctly, which is probably what you are referring to.

How big is the PN-profile buffer size and can this be turned off without affecting the profile?

Quote from: Blim There are not other factors involved?
Like what ?
There is limited bandwidth to your modem, your Plusnet profile is almost 100% of that maximum datarate, and the QoS seeks to fill that available bandwidth in the most intelligent manner. What else do you think there might be ?

Why would you want to switch any buffering off ? the alternative would be dropped packets that in turn would cause your PC to request resends.
Those resends then take up capacity on both your upload and download streams with unnecessary additional load, further reducing your bandwidth.

Is it possible to turn this off then or tweaked in any way?

I don't understand what you want to switch off ?, or why ?

Its a know tweak in the gaming world to turn buffing off on a home router to prevent delay. Old routers never used it back in the day

That article, and the articles it refers to, appear to talk about problems from 20 years ago, and also why buffering causes latency when the ISP does not have sufficient bandwidth provision to support all the customers requirements at peak times.
However the network kit at Plusnet has immense throughput capability, and the effect on your individual line wouldn't be measurable, and Plusnet DO have sufficient bandwidth to support their current customer demands.
If you are NOT running your connection at 100% capacity, then buffering latency doesn't apply anyway.
Modern communication buffering systems have a latency of nearly zero, and if latency is experienced then it will be the time that it takes to send the data to you over the slowest part of the network, and not additional time added by the buffers themselves.
The buffering process actually increases throughput, by eliminating delays between successive packets.
The best thing to do to avoid latency is to maximise your connection's sync speed, and ensure your upstream rate is uncapped.
