Totally agree.

But I will say there is a difference between "we don't" and "we may".

A5X: I have run a new short RJ11 cable, new filter/splitter, and new quality CAT5e to my R7000 in the next room. Effectively there isn't any bad links remaining (if any) for the modem. There not much change to the stats when compared, Line Attenuation is half the value. Unfortunately I cannot go any faster than 15 Mbps using slingshot speed test (I do all my test from wired PC). I would expect the downloads to be the same peak. Certainly look like there is more in the tank but being held back.




I am late to the party on this one, but here is a few things to check and consider.


Checklist:
- Ensure frames are not being discarded due to (an assortment of) errors.
- Ensure your PC can actually process line rates in excess of 15 Mbps.  (Some older PCs can't handle much, especially when it is offloaded to the CPU.)
- Ensure you don't have any QoS or Shaping policies active on your router. (Some software implementations are dodgy. Or may be misconfigured.)
- Ensure modem / router is running the latest firmware.
- Ensure your new cabling avoids any extreme sources of interference, especially if it is not shielded cable.


Other Things to Do / Consider:
- The Alcatel equipment backplane in the cabinets are blocking. So if there are many subscribers will high speed connections, perhaps the line cards connection into the backplane is overloaded.  (Non blocking backplane is more expensive)
- The cabinet's backhaul is congested.  (ISP has to log an issue with Chorus)
- Software or Hardware issue at the cabinet.  (Ask for a port reset - works wonders.... you have no idea how many times this fixes a lot of things.)
- Try a different modem / router.
- Try a different PC.
- Use winmtr  ( http://sourceforge.net/projects/winmtr/ ) and see if any packet loss is occurring (might be a congested node with full egress queues).
- Try to copy a file between two PCs and check to see if the speed exceeds that of the ADSL2+ connection (localised speed test).



* If any of these have already been suggested then apologies for the overlap. (Just trying to summarise)

Sorry about that, an issue with my definition of throttling perhaps. There is nothing in place that will limit speed to a certain number. If prioritization is in play and there's heavy traffic on your network then attended traffic (browsing, gaming etc) will have a higher bandwidth priority than unattended traffic.

Throttling has often been used for shaping.

Prioritisation (eg QoS)   !=  Shaping.



Likely what Slingshot are doing involves the use of DPI to better classify traffic and map to egress queues.
When the network is congested, traffic (attended types in higher egress queues) are forwarded first before lower priority traffic.

There may also be a wrr egress queueing method.


They may be using other techniques too (limiting TCP connections etc) I could be completely wrong.



In my experience, p2p traffic goes between 2-4 Mb/s, steam traffic up to 5.5 Mb/s.
Not bad at all.

Torrents only go as fast as they are seeded. I do not mean to imply that Slingshot has a direct hand in discarding some of my traffic due to congestion.
It is encrypted so its likely being lumped into a lower queue (if congestion is occurring). Furthermore their DPI system is probably picking up on the p2p behaviour / pattern, so could be further deprioritised if identified as p2p traffic.

Both Origin and Steam download at 5.5 mb/s and you tube 1080p plays seamlessly.


I would say that 5.5 mb/s is near line speed as the theoretical limit for me (47 Mbps) is roughly 5.8 mb/s.
So minus the overhead etc its about right.

i was implying a decently seeded, non public swamped everyone leach the heck out of it torrent situation...

Slingshot: Hey OP,

We don't throttle any of our plans (unless something's changed and no one's told me which I doubt). You really don't seem to be getting as fast as I think you should though. I'd be happy to look at doing a VDSL deal for you if you want to flick me a message with your account number.

Cheers,
Chris

Plugged in the Slingshot generic modem model VB104W and has connected on ADSL for the time being. This particular model reports some bad attenuation numbers, where as the 3 other modems were very close to each other, the VB104W looking pretty bad. Line speed is down +3000 and the Up is reporting lower than what I would normally see.
