Ok, so I swapped from Slingshot to Xnet thinking that my ping couldn't get any worse and hopefully interleaving would give me a big decrease in ping. Well so far they are far better than slingshot (speed wise, and they don't enforce you to go through some crappy proxy making many sites unviewable) but ping seems awfully high in game (in this case BF2) ranging from 110-130...

On slingshot I was getting 90-100 which is still a joke, but 110-130 is even worse. I still have interleaving on (should be turned off within a few days...) but I was told it only reduces ping by 35-50 at the absolute maximum so i'd be back where I started at 90ish, where I was hoping for around 50 or less.

I am within a km to my exchange so distance should not be an issue, I am flatting with 5 other people in North Dunedin using a D-link DSL302Gv2 modem and some generic switch. When no one is using the net but me my ping is 110-130 and being plugged directly into the modem instead of through the switch gives no reduction.

I'm on the Max/128k plan with 25GB and i'm synced at 7616kbps (11db) downstream and 160kbps (24db) upstream giving me max speeds of about 3-3.5mbit at off-peak times and 1mbit on-peak (Dunedin has some serious bandwidth issues when it comes to speed vs the rest of NZ).
I'm not too worried about the speed, I just want to know why, on the same exchange, at the same address as I was on with slingshot a few days ago my ping has increased by about 20-40ish.
I also used to live 200m from here with Xtra and get pings of 75-85...what is going on???

I've tried ringing up tech support (very prompt response btw, loads better than xtra/slingshot) and the techie told me I should be pinging 10-20ms to the recoil.net.nz server no matter where I am in NZ (seems unlikely), well I seem to get 110-130, the same ping to ICONZ/XTRA bf2 servers making it virtually unplayable.

I have also talked to 2 other people in Dunedin with Xnet, one who I think is on the same exchange getting 30-50ms ping, so why is mine so bad?

Recoil is in a WxC AS so if anything I would have thought your pings would improve. If you have a router which supports it try an ATM OAM ping to your dslam and the LNS to check if most of this latency is occuring there, if so then there is SFA you can do about it really.

I'm unsure how to perform a ATM OAM ping to my dslam on this router and I couldn't turn up anything useful on google so I assume it doesn't have the option to :(

Did the tech give you a ticket number? if not call back and ask them to look at it again.

I ping 50ms to recoil with interleaving on (from AK, with xnet).

What is your ping to the other end of the ppp link?
is it reasonable (<55ms)?

If not its something to do with the exchange/port you are on most likely.
Keep pestering Xnet support till they do something about it.
Eventually they will get telecom to change your DSL port.
This may help. But if the exchange is heavily oversubscribed/underprovisioned then you are pretty much SOL.

Ok well my interleaving is now off and i'm pinging 80-95ms to xnet.co.nz/game servers/recoil etc etc

A few others i've heard from in other forums from Dunedin have pings of 30-40 with interleaving off so I guess it's my exchange. Been exchanging PM's with a Xnet Techie (having an official Tech support willing to help through some random forums seems to be unheard of for most nz isps *hint hint* slingshot :P)in the GPforums and he reckons it's because of an overloaded exchange and trying to get telecom to do something about it (hopefully change dsl port *fingers crossed it'll work*)

Managed to find the ATM OAM ping option in my router after googling for the link which is hidden in the settings :/ Said pass, so there goes that theory :P

I highly doubt changing your dsl port will improve your situation.

It's far more likely, as you noted, to be a congestion issue.

Anyone know who Xnet peers with ?

Interleaving is a fundamentally important error correction scheme. I would never disable it on my connection, for the sake of 10 milliseconds you are introducing the possibility of many errors.

By many errors you mean like 2 over 6 months right? Mate of mine has had interleaving off since it was first offered by Orcon and never had a corrupted download or a major bung up in connection. It reduces ping by 30-40ish usually, definitely worth it in my opinion if you do any online gaming whatsoever :)
Yet to see any errors for me also (although only been a week :P)

most people will not see any errors on an un-interleaved connection, but there will be cases where the lack of error correction will cause problems, particularly in long-reach ADSL installations and oversubscribed-copper areas.

to put it in gaming terms; while the ping is lower, lag "spikes" (a time-period of packet delay or loss) are more likely on an un-interleaved connection. you are trading off reliability for latency but i agree you would probably want to do that for gaming :-)

although if your connection is unstable with interleaving on then the issue resides elsewhere

I'm on the Max/128k

Thats the start of the problem right there (128up). The other problem will most likely be at your exchange and/or the amount of traffic.

Also some uninterleaved connections do experience packet loss and a whole heap of CRC errors, especially when playing games :)
