Good settings on Netlimiter

What are good settings to use on Netlimiter? i have installed the trial version but have no idea what the proper settings should be.

this post should have been post in off topic.

read the manual..., the last time i check netlimiter had a help menu.
netlimiter web site is also a good place to look.

What is your maximum upload rate for your DSL? Set the max upload for DC++ to 90% of your overall max upload. See if that helps the download speed. If not, lower it until your download speed is solid.

maximum upload is 256kbps

Click in the "Up limit" column in the row marked "Overall" (at the top of the GUI) . There you can set it to 210-230kbps.

Moved.

It might be better to just limit the upload speed of DC++, not the overall.

Netlimiter works in kBYTES per second, not kBITs, so 256/8 = 32kBps. So maybe 29 or 30 would be an appropriate speed.

Your calculus is too theoretical Xan. You have to adjust for protocol overhead. For my ADSL line it works very near to reality if you dived your max capacity with 10. So for my 512 kbps I get pretty near to 52 KBytes/s as max. So for 256 kbps it would not be good with 29-30 KBytes/s. Best of course to test and see when you get the desired effect ... I think around 23 KBytes/s.

I don't see anything wrong with Xan's description - divide by 8 to get the maximum potential speed, then set the limit to 90% of that... Though I'm personally at 80% normally of my 128kbit/s line.

In any case, I hope people realize they can lower/increase the limit per their individual lines, since I've been on cable and DSL and both had different sweet spots for uploads not affecting download speeds.

Well for one thing, you loose 1 bit guaranteed as stopbit in the ADSL protocol. Then you have at least 3-4 % loss in IP/TCP header overhead. Do you mean that you have seen anything more than 13 KBytes/s on your 128 kbit/s line (if uncompressed transfere) ?

Yes, I removed my cap for a half-hour or so:

That's the traffic graph from my router, and a speed from the only upload I have at the moment... It fluctuates a little - going down to 15k, but the graph above is accurate.

I think we see in your graph the total bitrate, including protocol headers.
When specifying in Netlimiter I believe it is data bitrate, without the protocol headers, that is active. This is only my guessing from being unable to get anything higher than 52 KBytes/s out of the Netlimiter reading when uncapped and making sure I feed my download with a connection much faster. This also corresponds very neat to the good thumb rule of getting 80% effective data rate out of the nominal connection bit rate.
Let me also revert on my hidious statment about ADSL protocol stopbit overhead. This was just me jumping to wrong conclusion trying to understand the nitty bitty details of the protocol. When you give it a small time of second thought it's obvious you couldn't allow a gross 10% protocol overhead in the physical layer. I was just way back in RS232 land, may it RIP. The protocol overhead of ADSL is 1 byte out of 68 which is bad enough ....
So,back to post issue, I'll stick to my theory that you have to operate on effective data rate when specifying in Netlimiter.

Just do a test. With too much ul the dl will drop significant so lower in steps of 1k to balance it.
