P2P Throttling Speed?

[nonroker]

For a few hours I thought I joined the "no bandwidth" bus.
Download/Browsing speeds were horrible.

So I went back in history to see what I did just before the speed suddenly went downhill...

All I did, was I started a Bittorrent download.

Check the difference

Before BT download:
Start Time: 17:08:09
End time: 17:08:22
Download Size: 204800 bytes
Time Delta: 13.09633398056 seconds
Download Speed: 15 KBytes/s
Line Speed: 120 kbits/s

After BT download started:
Start Time: 17:08:25
End time: 17:08:00
Download Size: 204800 bytes
Time Delta: 154.20679306984 seconds
Download Speed: 1 KBytes/s
Line Speed: 8 kbits/s

The BT was downloading at 1KB/s and uploading at 8KB/s
But I'm on the 256k package, so what happend here?

As soon as I stop the BT download, I'm back to normal Browsing speeds.

IF Sentech is punishing P2P users by chucking them in a starved bandwidth pool, then they should publish this somewhere.

I'd like to see their Network policies on their web site.

Sentch cant set up a mail server, how on earth are they going to throttle certain applications or ports.

Seriously, I dont think this is true since I download tons off Bit torrent and while it goes at 12 I still surf (although very slowly) and I am on a 128K package.

 

[nonroker]

Well..I just started the download again, but on a different port from the standard and it took me about 2 minutes to open this post.
The BT download is running at 400bytes/sec and uploading at 2.4KB/s

Explain that?

Sure, Easy ......

MyWireless Sucks!!! []

 

[nonroker]

ahhhhhhh

THAT's why... []

 

[aborg]

nonroker - no problem here with BT

some ppl are just damn unlucky []

btw speeds seem to be back to normal after 2 weeks of really up and down moments. I must say ftp still sucks... thats my problem.

 

[guest2013-1]

avg about 27kb/s down and 30kb/s up, might be the seeds or what have you thats making my downloads so slow, but yea, generally not as nippy as usual.

Sentech, 99% downtime guarunteed!

 

[nonroker]

ah...then I suspect sentech's just "moved" the bottle neck to other towers to get the complainers to stop moaning, cept now they're creating new ones []

 

[gripen]

we're discussing the basic traffic management system. My theory is that there is a nice bandwidth pool. It does seem (after some analysis) that this is a traffic sensitive or traffic-aware system. Oftentimes I have seen horribly slow emule speed then if I fire up a BT or two the speed goes up to 14KB/sec. Now I am a rather experienced user with this so dont say "but emule is slow". I have been around long enough to know whats going on. With about 50 files totalling some GBs it still goes slow during emule throttle times then later on it picks up nicely again once the connections dont time out.

I cant say though that I have had slow emule/BT and fast browsing so its still unlikely that they are shaping BUT I do seem to nice a rise in my graphs when opening normal HTTP download connections. Honestly, since they are secretive about this big fix, I wouldnt be surprised if they were going to contend P2P and shape P2P traffic.

 

[nonroker]

My problem is either BT is fscking up my browsing experience or Sentech took my tower's microwave backhaul and swopped it with Brixton's. Something that's completely new. Since up until Sunday I didn't have any speed issues.

I'm finding a similar thing to nonroker. My P2P stress test (2 weeks and counting) slowed down some time after 4am this morning. D/L dropped from about 50MB an hour to 12MB and then dropped further to around 8MB at 11am. After got home this evening, i tried to start more threads to get the D/L speed up again, but without success. When I started browsing I found that it was deathly slow. Stopped all threads on P2P and suddenly can browse again.....

Yo-yo effect seems more pronounced than ever: D/L varies between 90kbps and 0 randomly from second to second. Might just be coincidence but....


MW128, Tower <b>60</b>(Northpark Plaza), Signal:16%,S-N-L: 7, BER: 45%

As I always say. <h3>Same ****. Different billing month</h3>

agreed.

thats SOP arf9999.

15 days and counting down....

I am getting very similar results to nonroker, only more pronounced. Last night I tried downloading a 28MB file from tucows.saix.net using flashget. If I had no P2P software running, my download 'Screamed' along at an average of 240kbit/s on my 128k package as shown by DU Meter. As soon as I opened a P2P program (tried Shareazea, emule and BitTornado), my Flashget download would come to a screeching crawl of below 10kbit/s. Also the P2P downloads and uploads seldom go above 2KByte/s. If I shut down my P2P apps, a few minutes later Flashget was screaming along again. I have tried numerous different throttling settings in the P2P apps, limiting number of connections as well as throttling uploands and or downloads using NetLimiter, but whatever I try P2P crawls and makes everything else crawl at the same time. Any Ideas?

 

[Perdition]

This may be more a result of tcp/ip crapping its pants (as first stated by Rodent) than Sentech doing any throttling. P2P apps in general open a LOT of connections, even if it is just a quick connection to check if a peer is still alive. As a result of packet loss these connections may be incurring far more overhead than they would in a 0% packet loss environment. This may be indicative of the fact that not everyone is having bad speeds with P2P.

 

[regardtv]

Agreed Perdition...

Some time back quite a few posting regarding this were made. I have been able to improve performance by reducing the "hard limits" of connections etc.

 

[gripen]

I half agree. To an extent the hard limiting works but still I find that it all depends on the network. I change no settings ever and about 20% of the time P2P emule will scream and suck the other 80%. This is independent of BT or browsing or anything EXCEPT network conditions.

In summary, you are most likely doing nothing <i>wrong</i> or there isnt much you can do. Blame the network.

Chuck that DUMeter. Theres no way on earth you can get over 128kbps (the hard cap is one of the things that actually work.. sadly)

 

[nonroker]

I've seen TCP/IP perform much better on worse lines (read: higher PL)
Like I said..I'd like to see the network policy online.....
