Opinions on "traffic shaping" software (e.g. cFosSpeed) for SLOW speed


Recommended Posts

I have a speeding problem (outlined under topic: Novice Torrentor having Connection & Speed problems! http://forum.utorrent.com/viewtopic.php?id=39498). I can't port forward as it turns out (almost certainly) that I don't have a router (I use a EVDO/3G modem to connect) - it seems I'm behind some sort of ISP NAT firewall (I'm trying to verify this with my ISP).

Meanwhile I came across this topic: http://forum.utorrent.com/viewtopic.php?id=10872 from 2006 (things may have changed since) which mentioned something called "traffic shaping software" (cFosSpeed was mentioned: http://www.cfos.de/speed/cfosspeed_e.htm). phaelox said: "Not a lot of routers have traffic shaping built-in yet, but there are software solutions such as cFosSpeed". There's other software, inc. freeware, that I found on Google: http://www.google.com/search?hl=en&q=traffic+shaping+software.

A lot of the forum topics talks about traffic shaping by ISPs. I'm talking about traffic on my own laptop. A lot of of talk about get the best out of already fast connection speeds (vs. my relatively slow one). My Connection speeds: 70KB/s DL, 9KBs UL, my uTorrent speeds: c. 10-15KBs DL & 6KBs UL.

So questions: Does anyone uses this type of software on SLOW speeds and did it made any consistent difference? And what software did you use?

I've heard it causes uTorrent to have a slow memory or handle leak in the past...but that may be fixed now.

Even besides that, uTorrent doesn't know what limits you're forcing on it outside of the program using cFosSpeed...so it will repeatedly try to go faster than those limits UNLESS TOLD OTHERWISE.

It is extremely important to limit upload speed at or below (below so you can do other things with your connection) the max sustainable upload speed as measured by speed tests and trial-and-error in uTorrent. Sometimes a speed test will say a higher speed than uTorrent can sustain. Peak bursts can't be counted on.
