Title: Slow Upload, Fast Download
Post by: AnotherMuleUser on May 18, 2006, 02:01:47 AM
I'm getting good download speeds :), but my uploads seem to settle around an average of ~1 KB/s per upload connection regardless of how large I make the slots ?(.

I have a cable connection; it seems far from saturated, and my computer (running MacOSX 10.3.9) does not appear to be slowing appreciably from the load.

Should my uploads be higher, or is it the case that most clients are on dial-up and so my upload rate is limited at their end?

If this is normal, then I wonder if the slot configuration should have finer granularity. eg. setting the slot bandwidth +/- 0.1 KB/s, or specifying the number of slots directly.

ie., after experimenting with a variety of configuration settings...
UB = Upload Bandwidth setting
BS = Bandwidth per Slot setting
AU = Average Upload Rate (according to the statistics)
NS = expected number of slots (calculated)
US = Average Upload Rate per slot (calculated)

Code: [Select]
UB  BS  AU   NS   US
10  1   7.5  10   0.8
12  1   9.5  12   0.8  
16  1   16   16   1.0
18  1   15   18   0.8
24  1   22   24   0.9
12  2    5    6   0.8
16  2    7    8   0.9
24  2   10   12   0.8
48  3   18   16   1.1
70  7    8   10   0.8
Thx  :baby:

I don't think it's normal.  Certainly, there are some clients who can't accomodate faster uploads from you, but most can.

I would suspect bandwidth limiting by your ISP.  Try changing the ports that aMule is using.

I tried various port settings, all with the same result, and had given up.

My uploads would send about 67KB in the first couple of seconds, then nothing until a minute had passed; after that, I was getting about 1KB/s per client. I could set up 50 client slots (or more) and get 1KB/s each, but I couldn't get a higher rate per client with fewer slots. Evidently my cable ISP is bandwidth limiting to about 1 KB/s per IP address for extended transfers.

Then I noticed one particular client was getting uploads at 50KB/s over an extended period. Getting the details for the client showed he had set his port to 6881.

I then set my TCP port to 6881, and now my uploads are nice and fast!

From other postings on the internet, I surmise that this particular port is used by my particular cable ISP's VOIP service, and so it is (currently) immune to their bandwidth limiting.

Apparently the VOIP port varies from ISP to ISP, so you may need to research your local ISP to determine if they have such a VOIP port. If all else fails, watch your uploads for a client that is getting a good speed, and see what port they are using.

Cheers!

Funny thing is that 6881 is the default port for Bittorrent... ^^
