I just got....

I was doing some reading today about the incoming ports, it made alot of sense. Basically without the ports forwarded, youre only recieving data from people you are sending data to. Because there is an existing TCP connection, from you sending data out through the firewall, they then can send data back through. I opened the default tcp ports (6881-6999) on my firewall, and like you saw as well, saw a green connection for the first time.

I also did some reading about bandwith. If you are using all of your upstream bandwidth, that can slow down the downstream as well. They reccomend setting the Global upstream cap at 80% of your upstream bandwith limit. I have cable, and my upstream is 256Kbps, so I set my upstream around 26KBps.

So I had to go to work for a team meeting, but when I left ABC was well ahead of Shareza, in my little race. ABC is performing great with those two tweaks, so much so, I uninstalled sucksa.

I've read that too... I don't know enough about connections, but is that also true for ADSL? I thought ADSL lines had fixed speeds for Up and Down which are independent of eachother??

just out of curiosity... was Shareaza reporting higher transfer speeds despite losing the race?

p.s.- I had something like a 30-40% chance of getting bad CRC files with Shareaza (especially for large downloads containing alot of rar files). A week into using ABC downloading tons of stuff and have yet to get a single bum file...

[McNevin]

Shareza did alot of bouncing around with the eta. But filesize for filesize, at the time i left ABC's file was bigger. ABC reported 15 minutes left, and shareza 30. Started the exact same time, with the same torrent file.

To create multiple channels, ADSL modems divide the available bandwidth of a telephone line in one of two ways---frequency-division multiplexing (FDM) or echo cancellation---as shown in Figure 15-4. FDM assigns one band for upstream data and another band for downstream data. The downstream path is then divided by time-division multiplexing into one or more high-speed channels and one or more low-speed channels. The upstream path is also multiplexed into corresponding low-speed channels. Echo cancellation assigns the upstream band to overlap the downstream, and separates the two by means of local echo cancellation, a technique well known in V.32 and V.34 modems. With either technique, ADSL splits off a 4 kHz region for basic telephone service at the DC end of the band.

ADSL just means the speeds are not equal, as in SDSL where your up is the same speed as your down. ADSL uses the same line for downstream and upstream, but just different areas of the bandwith of that line. The same is true with cable, there is a dedicated 6mhz range of bandwith for up, and 6 for down. The difference between the two is dsl has an independent connection to the Central Office, and then it is shared from there throught the rest of the network. whereas cable is shared from the pole to destination. Thats why the more people on a street that have cable internet the slower it goes is the myth.

So if i were you i'd try capping the global upload rate.

So from what I gather, Cable and ADSL UL/DL streams share the same bandwidth. thanks for the breakdown.... I'm gonna mess with my global upload settings later... see what happens.

After you capped your UL speed, how fast has ABC been (what kind of rates Kb/s)?

[McNevin]

Getting 50 KBps on ninja gaiden iNSOMNiA currently.

With the official client, i never saw anything higher than 12-15KB, but that is before the port forward and upload cap. i have noticed that web browsing is alot better with the cap, it leaves 20% of upstream bandwith for the occasional url submittal. I had noticed that BT was slowing down my surfing, so I am sure I was flooding my connection.

I got better "reported" speeds in shareza, but they were not stable, the line graph was all over the place. It was hard to actually know what my average speed was.

The test file was considerably slower (7KBps in ABC,) but there were only about 5 peers on that one. it was 50 megs.

What speeds are you seeing.

[mistasparkle*]

bout the same... Had Shareaza report speeds up to 2Mb/s which in actuality is probably way less.... I've seen ABC go as high as 200+ Kb/s, but the averarage is between 20-70Kb/s

[enderzero]

I have 6881-6999 forwarded. I found that with Shareaza if I let my uploads go uncapped it would crush my system performance to the point of almost making it unusable. I capped it around 50-100kbps but still regularly see burst uploads around 200-300kbps. You should give Azureus a try as well.

My bigggest concern is resource consumption (over speed gain). I may have some sort of memory leak (may be in shareaza itself) because my performance gets hit hard after I max it out (usually means having open: Shareaza, Outlook, Firefox, ACDSee, Photoshop, Winamp, Messenger, Dreamweaver) and then close everything down. How do the others you have tried do with memory?

[mistasparkle*]

ABC bogs down my system when it verifies large files at startup. Other than that it doesn't do the kind of performance damage that shareaza does when its going all out...


p.s.-Are you back??

[McNevin]

I had to reboot my pc after using bit torrent for several days solid.

That included the use of all 3 clients, so im not sure who was the culprit.

I finally got the ninja, its awesome.

[McNevin]

So the Official 3.4.1 bt client is out. But its pretty lame. Still has the lost tracker error.

Dont even bother, stick with ABC.

[enderzero]

mista* - yes

How goes the client search? Has everyopne switched to ABC then? I will get that crankin if I ever have reliable broadband internet again.

[McNevin]

So i tried Azureus today... it looks great, and has tons of cool features.

The only problem, which is a very big problem, it takes forever to resume / check a partial torrent.

Any tips you guys have on this?

Thats weird. I thought ABC was much slower at resuming/checking downloads. Azureus is generally pretty quick about that.

[McNevin]

It actually resumes way fast! it modifies the torrent to be able to very quickly resume.

What i was having a problem with was reseeding a torrent that was not created by azureus. or an incomplete torrent started by another client.
