Is the first time i write on this forum. I have the new test version,
I have a broadband cable 4096/256 KBs.
I think the most, the old one, 4.8.2 was better for me in terms of downloads,, I don´t know of sure but Ibelieve i have a problem of Trafic shaping in portugal. I think with this new version, i have a litle less speed of downloads than with th older one, My upload are the same as the older one, i didn´t change anything from 4.8.2 to 5.1 beta.
Until now, 3 days without problems or crashes.
Now, my extrem is running very well, after i pached my tcpip.
If i may say, is the best mod i ever used.

I´m gonna to write in english.
This is the best mod i ever new. My only problem is the traffic shaping from netcabo.pt. I have no problems with uploads, but i have problems qith downloads, beacuse they ar´nt stable.

Hello,

Can you explain me what is the "Upload Management" in the "Xtreme I" section in the options?
I have only 16 KB/s upload bandwidth, how should I configure this section for best results?

have a look at the Xtreme-Homepage
all settings are explaind.. also in english language.

Thanks a lot!!!!!
But I couldn't understand one thing:
I have little upload bandwidth (16 KB/s), and I've got the NAFC enabled.
Which sendbuffer is recommended for me?

I recommend the standard-value of 8192

Hi Xman!

I've found a problem, when uploading and there are few clients downloading from me xtreme doesnt use all bandwith if some has slow downloading, if a few clients downloads like 2-3k and most can download much faster they dont get all speed that they can recieve, instead they only get about 25-30k and thus only using ½ of my totalt upload. It only happens when i dont have any in cueue, and about 25-40 dowloading, if it is very few (like less than 10) they get maximum speed they can recieve.

I've found that 10k gives me best stability in uploadspeed.

Yes, the uploadspeed gets instable, but allways higher when there are very few clients then with 25-40 clients. With that amount the uploads stays stable at 500-600kbyte/s, if there are more i get stable at 900kbyte/s and with fewer its unstable between 750 and 900 depeending on how much they actually can recieve.

And when there are that magic number inbetween youll se that uploadspeed to those who can recieve massive is the same for all fast clients. Normally 25-30k, if there are fewer and the same guys are downloading they get over 100k without a problem.

In this (normal) case is there an empty waitingqueue? And is the slotspeed most of clients at your adjusted value of 10k?

At the other cases what happen if you disable the option "open more slots ..."?

Hallo Isengrim,

what I understand is:

empty Queue and

uploading to

< 25 clients --> upload instable @ 750-900 kb/s
25-40 clients --> upload stable @ 500-600 kb/s
> 40 clients --> upload stable @ 900 kb/s

slotspeed

< 25 clients --> a client gets what he can take, if this is 100k he gets it
25-40 clients --> (known) clients who can take 100k gets only 25-30k, the result is wasted (unused) bandwith
> 40 clients --> fast takers get 25-30k but since there are enough downloaders there is only a little bit of bandwith wasted

Is this correct or did I misunderstood you?

Kind regards
aalerich

aalerich, almost right on target

This line would be:
> 60 clients --> fast takers get 10-15k but since there are enough downloaders there is only a little bit of bandwith wasted

since I have 10k as slotspeed, havnt that much experience with 40-60 clients that i can say exactly how it is inbetween.

Use more slots is disabled and use double sendsize is enabled.

A picture with few clients, UL slot speed 10k, maximum UL 998.4.

As u can see, fast downloaders dont get the speed they could get.

I read it now for the fifth time.. but I don't get your problem.
You know yourself, that there are many clients which can't take the speed you want to give.. they are "blocking" to oftenly.
More uploading clients should always be-> more stable upload.

when I understand you right, you say
if only < 25 clients in upload your upload is higher than with ~40 clients ?
You should recheck it... maybe the 25 clients you saw first where all "non blocking" clients, and later you had many blocking clients.

In one of the next versions (not to soon) I'll add an additional info how often a client is blocking.

Edit:
and you should share more files! Maybe a patch in Xtreme is slowing down your upload... the full upload speed is only given free, when you have more than uploadlimit/uploadclients/2 slots opened. In your case this should be about ~50

Edit 2:
ok.. I looked through the code.. and I'm sure it is the patch which reduces the uplaod until you have reached the minimum of uploadslots. I only wonder why this problem doesn't exist with very few slots.
However last week I already changed this patch... in the next version you shouldn't have the problem any more.
