ADSL to NBN - Now Get Torrent Bandwidth 'waves'

blackfrancis75 on 10/06/2017 - 18:57

I just upgraded from ADSL2+ (avg 10Mbps) to NBN HFC (avg 90Mpbs).
I was using a Billion BiPAC7300N with ADSL and it served me well, so I bought a BiPac 8900X R3 to go with my HFC.
I find that Torrent traffic on my new connection is going in 'Waves', e.g. from 0 to 200K to 0 again about every minute. I experienced this before, and I'm aware the common solution is to limit the number of connections to around 10 and work your way up.
The problem is – this solution isn't working for me.
The old BiPAC7300N used to easily handle a setting of 25 connections per torrent, with multiple torrents.
Using the BiPac 8900X R3, I'm getting waves even under 5 connections per torrent with a single torrent running.

I'm using Private Internet Access (PIA) for VPN. Have tried several end nodes.

Is there some other cause for this 'waves' behaviour?
I can't believe it'd be at the ISP level since I'm with the same ISP as before (TPG)
Are there other settings I can try on the Router?

    Have you tried different ports?

    Have you tried without the VPN?

    First place I'd look is the BiPac 8900X R3.

    I have similar speed HFC to you and no issues with torrents - how does your router compare hardware wise with a Netgear R7000; is it in the same ballpark as far as performance?

    There is obviously some limiting factor at work here, maybe reduce your upload speed, globally, and per torrent.

    Have you tried turning it off then on again?

    I've tried without VPN, and limiting upload speed.
    The BiPac 8900X was recommended as the King of non-wifi Routers for HFC; it has a NAT size of 32360 and it aint cheap.
    I'll check my port-forwarding config as recommended by @scrimshaw

    OK - have found the smoking gun.
    I'm on Mac, and was using uTorrent for Mac.
    When I switch to Deluge - No Waves!
    I don't know exactly what default settings or configuration cause the behaviour (though I've tried changing almost every setting in uTorrent)
    But it's definitely down to the Client in this case.
    Thanks for the suggestions all. Hope this helps someone else.
