Poor speeds when uTorren STOPPED by scheduler.

Hi,

I'm staying in a rented room and they have Virgin cable. Whenever I start uTorrent, it slows the connection right down. Other people in the house cannot play games 'cos the ping time goes right up.

This happens EVEN WHEN UTORRENT IS SCHEDULED TO STOP. (sorry for shouting

to recap, uTorrent is saying "stopped by scheduler" it's not uploading or downloading anything, but the speed goes WAY down. Also, strangely as soon as I stop uTorrent the speed goes back up again.

Bizarre, eh?

S.

When stopped, run netstat from a command prompt. Do you still have people connected to your machine?

Loads of TIME_WAIT connections showing on the port I've allocated for incoming BT connections, so I assume yes.

Loads of SYN_SENT on ports in the 64000 range too.

My bro knows about this stuff and I had similar problem with BT, and its to do with your isp packet sniffing, they are basically looking at what kind of information your sending and if the packet sniffer detects p2p it will throttle your bandwidth to a very small amount, even if your not uploading or downloading because utorrent still sends stuff out when stopped, it has to be closed to get your speed back.

Now encryption will bypass the sniffer but be aware, sending encrypted data will bring you to the attention of the police because terrorist organizations always send their data encrypted.

VM cable doesn't have protocol based throttling, try again sir.

You're probably munching all the memory in either the router or the modem with your connections - drop the amount of connections uTorrent opens, and limit your upload to a very low rate to avoid causing jitter, be nice to your housemates their gaming is more time sensitive than your leeching!

I'm pretty sure it's not that though, as this only happens during the evening. (sorry forgot to mention that initially) and it all works fine during the day. I'm pretty sure it's Virgin doing packet shaping, but it's annoying 'cos I like to leave uTorrent running so I can connect remotely if I want to kick off a (purely legal) download.

Also, I would like to point out that the housemates are 10x worse leachers than I am.

Nah, I've said my piece, you can tell us why...

Really!?

Well, that blows my theory then. Why would running utorrent make ping times shoot up to 100s of m/s?

Perhaps I should just try another client that supports scheduling (so I'm considerate in the evenings) and remove connections.

Suggestions, anyone?

1. Force Outgoing Encryption on utorrent (might work or might work sometimes or not at all)
2. The router might be able to schedule your connection, like the child settings, something like that.
3. Might be able to schedule your firewall, or get one that does.
