我用緊BB100，
BT上下載時會耐不耐有段流量真空期。
可能上下載而家4~5MB/s，忽然間係咁減到零………維持一陣，個速度又上返…………跟着又減過

週期性，應該唔係我連唔到seed/peer
發生咩事？

OS : Win7 x64
Lan Card : Onboard Broadcom
ISP : BB100
BT Client : utorrent 2.02
Router : WZR-HP-G300NH

本身都有依個情況 (無用ROUTER 都係今) 係當有一個USER 大量UPLOAD 比你
但係其他無UPLOAD 比你時候果個USER 一斷就跌好正常事

BT REQUEST 邊有PART 去DOWNLOAD 係UTORRENT AUTO 做
自己無權去干預佢 ACCESS OR DECLINE

但其實我係做種的，而且一次成十粒………

佢係一次過全部種的UL Rate跌到零
過左一陣又全部一齊上返幾MB…………

HW問題多我估係做咗個保護防止有事
要做PACKET CAPTURE 睇下點解會今樣
先知道點解佢自己斷

我都買咗你個型號ROUTER 我未有時間開箱做TEST

作者: ccw 時間: 2010-7-11 01:37

Here are some pictures describing the situation:
-Only utorrent is opened during the test.
-Refresh rate of Task Manager is set to High

First pictures:

As you can see, it drop to zero after some time and then restore.
And this is a cycle, happening once in ten minutes.

作者: hungjoyee 時間: 2010-7-11 16:13

我睇到喎
我想問有無唔經ROUTER 情況之下做TEST ?

依個有兩個可能性出現一有軟件截你流量要CHECK
二係HW 問題

Can you see the pictures now?

For the router, as my brother is using his computer, I cannot detach it at the moment, I will have to test it later.
Thank you for your advice.

如果可以話用WINDOWS 7 RESOURCE MONITOR 因為比較DETAIL 而且你會睇到個邊個PROGRAM RUN 住個NETWORK

I have been using the BT without a router for one day...........
No abnormal speed drop at all.
It seems it\'s my router\'s issue.

ROUTER 做咗保護今就麻煩啦

我想問你用DD-WRT 定 official firmware ?

Official only.
Just wanna see if the later dd-wrt can solve this.

I am raising a question Buffalo Forum, maybe people there can have some sorts of solutions.

今要等下啦因為好快出DD-WRT firmware
到時候我會做白老鼠做test

今日終於搭咗個network 我覺得隻router 好掂
不過vpn 得 pptp 係遺憾黎如果l2tp 仲好

作者: ccw 時間: 2010-7-13 00:00

Although I don\'t think that it is related,
after I restore the default DNS from Google\'s to factory default, the problem seems disappear even I am with the router, I will have to test it for some days before I can come to a conclusion.

作者: ccw 時間: 2010-7-13 19:19

Oh my god, upon my latest test, it is not the rotuer\'s issue, it happens again without router connected.

Will changing MAC help?
I am trying to test if this help.

In the opening I connect without the router the speed is ok, but after some time it happenes again......I now try another IP to see if it affects.

作者: ccw 時間: 2010-7-13 20:08

BTW, it affect only the UL rate but has no effect on the DL rate, I mean the speed drop

作者: ccw 時間: 2010-7-13 20:27

After changing the MAC and IP, it seems fine......

作者: ccw 時間: 2010-7-13 20:55

Yellow : DL Speed
Red : UL Speed

No router used, no anti-virus/firewall...........
Utorrent 2.02
7 seeds uploading...........

唔通係隻BT軟件出事？
我親佢上載零哂個段時間做HKIX2嗰個上傳速度測試，又似無事

我覺得係HKBN 有問題

你試下用BITTORRENT
唔好用BT 睇下點

Communicating with HKBN........

I may try other clients later but as I am playing on a PT, it allows me a few clients only and the best(at least up-to-date) is utorrent.

Btw, I am now uploading ~200GB of data via BT everyday..........is it dangerous that HKBN will trap me due to this?
Thank you.

作者: ccw 時間: 2010-7-14 16:42

Upon my latest test,

the upload speed is less likely to drop when there is only one seed uploading, even at a high speed,

the upload speed dropped obviously when a lot of seed are uploading, even the speed is not that high.

似係軟件問題

不過有無試過其他BT 軟件 ?

I tried another BT client called BitSpirit, downloading the same file with utorrent,
if only one file is being downloaded at the same time in each client,
NO speed drop is found.

But if I switch on other jobs in utorrent, speed drop occurs.
I cannot try to move the other jobs in utorrent to BitSpirit as BitSpirit is not a recognized client by the Private Tracker.

I think in the later time I will need to do a more detailed test with non-PT files.

作者: ccw 時間: 2010-7-14 18:25

Some clues showing that it is more likely a software issue:

1.

The red line represent UL rate while yellow represent DL rate.
The concern here is UL rate only.
Both utorrent and Bitspirit are opened.
Utorrent is doing 9 jobs while Bitspirit is doing one job(one of the seeding work same in utorrent, not from the PT)

The flow does not drop to zero as BitSpirit could still upload when utorrent dropped.

本身個軟件有缺陷

你試下用A字頭用JAVA 寫個隻因為UTORRENT 有外國開始BAN 佢因為佢個UHT 問題

I see, I will try more clients later.
A problem make me stay at utorrent is that it is the best allowed in the PT

作者: ccw 時間: 2010-7-14 20:35

Luckily Azureus is newly added to the allowed list, I will try this, thank you for your suggestion.

作者: ccw 時間: 2010-7-14 21:37

Just tried the Vuze - the client written in Java........
I don\'t know why my system crush with it.
First, the download speed drop to zero after a few seconds it started,
I cannot stop any of the jobs, the jobs show "Stopping" endlessly.
Finally, I can\'t even close it, even I terminate it in task manager, it does not work.

Maybe I need another substitute.

Vuze =/= Azureus?

Or it is another Axxx client?

Maybe I try to update my Java first, thank you so much for your advice.

作者: ccw 時間: 2010-7-20 01:30

Finally
It seems I have got the key.........
The ram cache.

After having some discussions with guys in utorrent forum, they suggested
disabling the functions of utorrent to see if they affect.

After tweaking the network part I had no luck at all, I try to switch off the reading cache for uploading.............and the drop seems disappeared(still need some days to confirm)
While I do think that it is quite reasonable, if the upload read from cache while the data of the cache is not updated in time, especially for high speed uploading/many upload tasks, even 1GB of ram cache would be very inadequate............and if the program itself is unable to mange, upload maybe disturbed.
Just my guess but I do hope this annoying thing has really gone.

Thank you for your kind attention.

至於打柴，都無所謂，係隻純動物Harddisk，早就有為成就大業而犧牲的覺悟。

我無你今有錢我小眾人仕都係行RAM CACHE 保住隻HD

作者: ccw 時間: 2010-7-22 18:47

Finally, I figured out the key.
The reading cache can still be applied..........just uncheck these boxes in blue:

The moderator in utorrent forum also suggested that the second box in the window above(Reduce memory usage...) should be unchecked as it reduced TOO much memory.
