More sources and segments

[Olorin 0]

I have gigabit adapter linked at gigabit. I have 50-100 sources at the hub. But I can use only 10.

1 source makes 1-10 megabytes per second

10 sources make 10-100 megabytes per second.

So real speed is 2-5 MB/s.

And I can utilisate up to 16.5 MB/s on my 4xIDE133 striped HDD on PCI33 controller.The limitation because the 32 bit PCI33 link speed equal 133 Mbit/s

And you with SATA300 HDD theoretically can utilisate up to 33MB/s NOW! (Real speed is not so big of course )

Next generation SATA makes links with 600Mbit/s so only 2 striped HDD will be able to utilisate 150MB/s (oh... 120-125MB/s - it's critical to copper Twisted Pair). Yes, up to 150 MB/s because the current raw HDD R/W speed is 960-1100 Mbit/s - read you HDD description, read specs at manufature sites.

Referring to NAND flash researches access time can be 50ms. I means the speed will be great.

So the number of sources should be increased.

Definitely NOT and it doesn't have anything with hardware capabilities. It had been discussed a lot in the past so make some effort and search.

(and there's no "get Your hands away from max segments" option in the pool..)

sorry you are right.

Help me searching, please. - My native is russian.

DC was never supposed to be like torrent and such that allow u to download off 100 users at once.

In fact, this would kill DC, it would mean a user with this capability cud take a slot from every user in hub.

DC hubs vary so much in user size and they also dont have to connect to many hubs.

Problem is a user in a few hubs, dling 5 files with 50 segements in each is using 250 users! in a small hub this would be the equiv of a slot from every user....

you are right. But where is the problem? I can't understand the idea. Why the multisource will kill the dc? If the kademlia.dll is, if unlimited dayDC (for example) is.

I have already found the forum discussions and even now I can't understand, where the problem?

May be if downloading is slow the shareing time for leechers is greater? Don't forget that Apex can upload unfinished files now - this is a step to real multisource.

after 2 hours of reading I think 5-10 links is good enough. And after 2 years of DC clients using I think "autodisconnect" should be on by default with rules rated with percents.

Apex does not support kademlia. Many hub owners consider it a no no.

Also, many ops also think multi-source is bad. But not if correctly implemented.

I'm operator.

I don't think ops and owners at our LAN care about multisource. The most problem is connectivity - users don't know anything about routes or connection settings at cliens. The second problem is "bad words", porno and "medved's sleng" at chats. Also ISP grows intensive and extensive ways, buying small competitors. Metro is growing about 25000wks per quarter. And we have all the problems caused. So the routing and the peering problems are more interesting... Our main links are 10Gbits ( %-/ ). The userbeasts population at our LAN comes to 100 000 workstations now - netbynet Moscow. And more than 50% are lamers! More than 95% are newbies. That is the real situation at LAN ISP market in Moscow. We have 4 large ISPs with metronets.

And multisource is important for users, not for operators, ISPs or anybody else.

DC users number is growing and now is coming up to 4000-10000 sorry for approximation. - Too much hubs.

This look's like a cool MAN network. Sounds like fun.. how much DC users?

Anyway... instead of increasing segments, You should focus on disconnecting slow downloads.

There are there several options affecting this behavior, in:

Settings >> Downloads

Settings >> Queue

Settings >> Limits
