bit torent slow over lan?

[Mellman]

I run a BT tracker on a win2k3 machine, for local lan based transfers only, to distribute large files (500mb - 5GB) the tracker itself works fine, but it seems that the seeding of the files is horribly slow. using FTP, i am able to acheive full transfer speeds, quite close the the 12.5 MB/sec limit on 100Mbit. However using bt, on the same machine seeding to any number of clients, the total speed of the torrent rarely exceeds 1000KB's, even with super seed mode on. has anyone else experienced this? I've tried serveral clients, shadows, abc's, experimental, original, and a few others, only one i havnt tried is that azerous. it just doesnt make sense to me how an ftp xfer can be so fast, and bit torrent manages to slow things down, does BT somehow create more overhead then TCP/IP? BAH....even with multiple seeds, (3-4) one client downloading doesnt manage above 3000KB/s

just bored...and not understanding this concept, yes ive looked at all the options on all the clients to ensure that it wasnt limiting bandwidth, connections, or anything of that nature.

Thanks,
-Matt

I'm not quite sure I understand you. Are you saying your dl speeds never exceed 1 MB/s? Or that you are seeding and your upload never exceeds that?

In my experience it is truly a rare thing to ever get a dl speed of over 100 kb/s on bt, and I've gotten 1 MB/s maybe twice.

However, I was having some trouble with my bt client (shadow's) causing bandwidth issues with multiple computers on a router, so I switched over to Azureus (the only client I have found that is NOT based on shadow's) and I love it. Clean interface, low resource use, and it doesn't seem to cause any internet problems.

He is on a LAN azndelite. He isnt transfering files over the net.

My guess would be that BT isnt truly designed to be used over a LAN instead of over the net.

So he is. I would agree...I can't even see why you would use bt on a LAN when u have an ftp that seems to work well.

Maybe your hard drive is thrashing? BitTorrent doesn't access files sequentially, and is brutal for hard drives at high transfer rates.
