@0x00,
Have you tried mods with slotfocus feature ?

[0x00]

@omeringen, no, I'm using a vanilla eMule.

Can you provide me with the links?

I did some thinking, and a 10MB emule chunk is good only for 5 seconds of upload at 2MB/s. Downloading is different, since you have a writeback cache, which gives you a performance boots. Something similar is not possible with uploading.

More than the actual number of slots, I think a better caching by eMule is needed. Windows caching is good, but the SW itself knows best, what it will use. The number of slots could also increase, if you get a lot of slower connections.

The number of slots is best intelligently managed within a range, specified by a user (you set min&max, the algorithm pick the current optimal setting). The point is that instead of dividing your 2MB/s to 40 people who can all take all 400KB/s each, it would be better to do a "round-robin" with 5 of them downloading at once.

A problem is eMule would usually not know what to cache.
- Who will be next to upload to
- what chunk(s) will they want from the file they are waiting for. (their decision)

Slotfocus will not let you define a range of slots, instead it tries to minimize # of slots by sending at highest possible speed to slot #1, then the same for slot#2, etc. until all bandwidth is used.
You will also have some "trickle slots" (~150 B/s) as a like reserve in slots, to fast compensate if fully served slots can not take as fast as expected.

I don't know if this is the case in Mods, but for these trickle slots, there caching could be effective, I think.
Maybe look for/ ask for a Mod that pre-loads full chunks into cache for trickle slots (if this exists) ?
Opinions ?

When it works well, I for example have 4 slots + 2 trickle slots @ 80 kB/s.
sometimes less, sometimes more.

The feature is explained fully here (old topic)

Sorry, I am not up-to-date with Mods, myself I use a simple Mod from Emule 0.49c version. Which I probably would not want to do on an connection as broad as yours.
Sadly, there is no newer version of Zzul-Mod, which to me is/was the kind of "cleanest" or "most simple" Mod, so easiest to learn to use.

There are so many, many Mods with slotfocus, but usually they all come with many more features, too.
best wait for so. else to recommend this one or that one ...

(. . .)

Check eMule Mods section.
There aren't that much mods based on latest official eMule. As far as i see there is MorphXT / StulleMule / Kmule / NetF WARP available.

I didn't expect such a hostile attitude.

Why it ccould not be expected that people with 'solutions' should know the subject?

With my current shared files set, I can have 30+ slots, and still would not fill 1MB/s upload.

With 150B/s a single block from disk read can give data for several seconds of upload.

Full 180KB pieces at a time could be used. Reading ahead whole 9MB is a doubtful idea.

But trickle slots will become fullspeed-slots, so eMule could/should know that it will need that whole chunk soon ?

What is your conclusion from that ?

That eMule just can not be used on very broad connections without limiting number of slots, even though that will mean often not using full bandwidth ?
respectively setting an UL limit way below capacity?

No, it cannot. You should not mix up 9MB chunk and 9MB upload limit.
It was explained in one of the 'endgame' topics, that eMule requests 3 180KB pieces at a time. Other peers may contribute to the same 9MB chunk or may not. You cannot know what pieces will be requested next time.

Obvious conclusion: there is no single magic number for every connection and every computer.
If someone is interested, today I saw 41 uploads slots could not use 1MB bandwidth. Will slotfocus help?

Just the other day, I had 76 uploads, of mostly different files - on 2200KB/s upload. I have unshared the video library to make the computer usable again

Haven't you checked slotfocus mods yet ?

That, or maybe fix that:

I'm just saying that the default emule settings are no good for today's fiber connections. Yes, I do have a SSD, but I have Windows 8 on it, which I don't like. So I'm still running Windows 7 off a HDD...

I mean, he complains about performance while he seems to have an unused SSD in his computer. Move Win7 to the SSD and eMule will have the HDD for it's up- and downloads. Problem fixed (probably).

Change ? Of course not. Everything works perfectly here. Never change horses in mid stream. Always keep with the winner: http://www.youtube.c...h?v=qABA0X6IzxU

That would be nice addition
