I seam to be getting a little better speeds with the ZZUL mod now.. And I read on the emule forum that disabling UPD might give better speeds, but I can't verify that yet.

But, WHAT IS IT? and how can I disable it to see if it makes any difference for me?

Its the User Datagram Protocol.

UDP is a on the same layer of network communcation as TCP (look at the 7 layer [in reality 5layer] model). It comes on layer3, after the pyschical connection and data-links [layer1] and the Internet Protocol [layer2]. Sitting ontop of TCP and UDP are the layer 4 elements, that being the services you are running, ie. HTTP:// FTP:// ssh, nntp, telnet, etc.. This is why it says TCP/IP, it is the transport level element running on the internet protocol.

It is a lot faster than tcp, but does not guarantee delivery of packets and some other flaws too. However, this doesn't matter in it's implementation into emule, source exchange doesn't really matter, it is a neat feature and means that you receive sources off of user emule users. Some of these UDP sources get lost in the system, as it were, but this is of absolutely no significance really as you receive the vast majority and reep the benefits :)

No data of the file itself is transfered by UDP, only sources where if you don't receive any data (be it via error, or any loss of packets) it doesn't matter. UDP in emule is used only for source exchange. The protocol should not be used for any important data transfer.

UDP increases bandwidth overhead however.

You can turn off udp, by turning off the option to exchange sources,probably on your connection tab.

I would leave it on though to be honest.

ps. TCP and UDP are ancient, barely changed since they were devised (60s I think?). Both have major flaws, and have huge overheads and thusly speed is inhibited. They are curently developing a replacement transport layer protocol capable of ultra-speeds. Hopefully it will emerge within 10 years or so.

It seams to me that emule will start up nice, and give better and better speeds, but at some point it clogs up and fall down again. currently getting 4.2 kb/s. =(

BH ver. 4 works great for me :twisted:

Even without the community option I mostly have HHAH members in my queue.

Your in it 9/10 John Doe for Jungle Holocuast and i get a minimum of 40K steady stream.

Perhaps it's your ISP, then. Busy line or they have bad connections.

Did you ever get steady high speeds John???

Becuase I downloaded Black Hand Version 3 unpacked it to a directory and then ran it.

The only change I made to ANY settings were :

max sources =1000 and max connections = 5000.

EVERYTHING ELSE WAS LEFT AS VANILLA FOR THE MOD!

I made no other changes and I get really fast speeds on SR files/ high sourced files!

What do you have it set to?

dittp about mostly HHAH people in the queue, i guess it's because we are all downloading the same stuff and therefore are uploading the same stuff to each other, getting higher positions in the qeues.

I've just tries out overnet (not the hybrid) for the past 2 days and am getting amazing speeds. not so many sources, but the ones you find give you a constant upload.

PS: I was a bit worried about the incopability of the partfiles that overnet makes, but the new converting utility in the kademila client makes these worries unjustified.

PPS: Yes, my typos is the outcome of my drunkedness... =)
