Downloading torrents killing internet

[As-21]

Hi there.

First what i have on the pfsense;

500 download 10 upload
q6600 4GB ram
and 500 GB HD

When i am downloading torrents even with slow download and upload speeds internet browsing is
not working and sites wont open, when i stop downloading it comes back.

I have tried fresh pfsense install with nothing except adding interfaces to it setup and getting the same problem.

When i switched the pfsense with DDWRT router the problem is gone and i can surf while downloading torrents.

What could be the problem ?

Are you saturating the upload link when that's happening?

You probably need shaping of some sort. Just enabling codelq may be sufficient. For example:

500/10 wow... Can you even hit 500 with only 10 up? Just the acks alone would suck up quite a bit of that pipe..

Torrents would kill that with such a limited upload if not highly contained..

I have 500/50 - I don't torrent from this connection. I torrent on a seedbox, and then just download to my PC from... This is going to be a better solution all the way around if you ask me with such a limited upload. And now you don't have to worry about your isp and any sort of "stuff" you might be downloading via torrents ;)

Just my opinion..

Nope upload is not even hitting 30kb.
Like i said on DD WRT this is not happening.
And yes i know 500/10 sucks but the best i have here i wish it had more upload for running VPN etc.

@Gertjan
Nope i just ran again while downloading torrents go this message:
"Failed to get servers available. Something may be blocking requests error:23
The browser failed to fetch the list of available servers. Either your connection went offline or there is a proxy or other browser extension blocking the test. If this error occurs after a successful test then there is probably a temporary resource exhaustion in the browser, OS or router."

when i was able to run it 11 connections failed and 6 successful.

Ill try the codelq and report result with it.

I think doing a codelq scheduler and 520Mb in Traffic Shaper on the WAN improved a lot although not perfect but much better while downloading.
Buffer bloat was A with codelq.

[Gertjan]

Do several tests with an "up queue" (limited at 10Mbit ?) - start using values like

and also a little bit above and beneath.

@Gertjan
i did 9500 on the upload and now its working with much smaller delay.
Buffer bloat is now A++ while downloading torrents.

I used this youtube video to set it up.

Nice. Did it help with connectivity whilst torrenting?

@stephenw10
yes it helped thanks for tip.
I started learning now about traffic shaping to see if i can do more to improve
performance and just to learn about it for fun :)
