Using NZBGet Debug latest version and using NewsDemon as NewsServer. Max connections set at 45.

I've tried downloading different stuff with different ages. I've tried 3 different SSL/Non-SSL ports and also tried switching between the EU and US NewsDemon server but I keep facing this issue. My max connection speed is around 5MB/s. I've observed that downloads would reach 4MB/s (that's what I've set scheduler to) and then drop to 0KB/s after a few seconds and then reach max speed again. This keeps on repeating.

I have the debug log file, where do I send it?

If you remove speed limit - how it works then?

Removing the speed limit fixes the problem entirely. CPU usage is 10-11% and free RAM is 2GB with speed limit so I don't know what's causing this.

Any way to fix this while keeping the speed limit in place?

• What is your speed when not limited?
• Click on remaining time (near speed) to bring up statistics, then click on 'Total downloaded'. Make a screenshot and post here.
• 45 connections is way to much for 4MB/s. Change to 6-10 connections and test if that helps.

1. I get up to 6MB/s when not limited (in the mornings) and 12MB/s (at night). My speeds double at night

3. Changed connections to 15. Didn't help at all. Here is a screenshot:

What exactly the problem is?
The graph looks OK and the average speed (calculated over 30 seconds) should be as configured.

Check the lower values on the graph. It keeps on going to zero speed when speed limit is active but it doesn't go to zero when speed isn't limited.

When speed limit is active: It goes to zero for a few seconds then jumps back to normal speed.

When speed limit is not active: Speed stays mostly constant.

Speed limiter isn't perfect and can't guarantee speed on per-second basis but at least it can keep the average speed calculated over larger time interval.

So this is normal? I don't face this problem with Deluge by the way.

As long the speed on main speed indicator is maintained the fluctuations on per-second graph are OK. Attempts to smooth the per-second graph would increase CPU load and that's not acceptable.

I just checked Sabnzbd and it works perfectly fine and keeps CPU usage under 10% as well. Not facing this issue with it. I think this issue with nzbget only started a few weeks ago but i don't know what I changed, if anything.

I don't think SAB has a data volume graph. If I remember correctly it has a speed graph and the speed shown there is probably an average speed calculated over multiple seconds.

Anyway I can't make the graph smoother.

Then maybe we can implement an option to disable the graph? I'm losing around 36MBs per minute because of speed falling to zero.

Graph doesn't slow down. Speed limiter does. If you need more speed increase the speed limit.

So concluding, this is normal behavior for speeds to fall to zero every few seconds and then stay like that for 2 seconds and then this keeps on repeating? It just seems so weird. I also checked using Networx to measure speed and it does actually fall to zero every few seconds.

I wonder how v21 (latest testing) performs in this regard. Can you test it?

@xinseo I have never had this issue. Using v21 stable right now and I have no issues.
