I can confirm that switching back to 1.0.3 from 1.1.0 (within a 5min timespan) restored the original download speed without making any other configuration changes. I will see if I can do some more testing, but it would help to know what exactly was changed. As I mentioned before, original observation showed the Recv-Q staying more full.safihre wrote:You switched back to 1.0.3 and it's still slow?
In that case there's a problem with your server or the specific download you are trying to get. Is it a very old one?
Because 1.0.3 has been installed over 120.000+ times and we had no reports of decreasing speed, so I think it's safe to say that version works for sure.

Re: speed limit changes
While downloading, SAB is constantly checking all the sockets and checking if they are ready to be read. The check (and all the other things that happen during 1 iteration of that while loop) is "expensive" and causes more CPU usage than nessecary, especially when it keeps doing checks (and other bookkeeping) while no sockets are ready to be processed.
So in 1.1.0, if less than 1/4th of connections say they are ready (or if your total #connections is 8 or lower), we apply a little delay so we check less often.
This causes a real nice reduction in CPU usage without limiting speeds.
What I hypothesise happens in your case is that we only read 32.000 bytes when a socket is ready (this has been the same since many many years), so possibly a socket has more information than we read from it but less than 1/4th is ready so we apply a delay.
Alternatively, it could be a problem with SSL. Do you use SSL?
Instead of asking about your config, maybe you can send me your log? If you export your log in 1.1.0 (not 1.0.3) it will include an anonymized copy of your settings,

Re: speed limit changes
Hi,
Ok I sent you my config via pm.
I would propose, if possible, to make this 'delay' a tuneable/enable/disable option for those not worried about CPU usage.

Re: speed limit changes
1.03 is is the version I've been using all along. The speed, sometimes, would go up to 4.2, but never up to 5.3 as it used to be last year (and when I had 50M).
Now I have over 200M and it just won't go over 3.2! And no, not on old NZBs, I tried with the most recent ones and the same thing happens.

Re: speed limit changes
@helcio maybe you can try nzbget or another newsreader? Because this starts to sound more like a provider issue, your usenet provider not being fast enough (did you pay for unlimited speed?) or your Internet provider limiting you.
What do you run sabnzbd on? A normal pc or a raspberry or something?

Re: speed limit changes
Yes, I can try another provider... but I've been using Astra for the past 10 years! It's always worked for me. I want to know what's wrong... and fix it. Yers, |I have ulimited speed. I use a normal PC -- an I-8.
It's reallyw weird. Whyen I reboot it, the speed goes up to 4.3 -- then, after a minute or so, it goes back to 1.2 and stays there no matter what.

Re: speed limit changes
I originally had a 30mbit VDSL connection and could get full download speed with 10 connections. When my VDSL connection was upgraded to 50mbit I had to increase the nr of connections to 20 to have full download speed. My provider is a Highwinds reseller.helcio wrote:Yes, I can try another provider... but I've been using Astra for the past 10 years! It's always worked for me.

Re: speed limit changes
I tried using 8 connections, then 20... nothing seems to help. I can't figure outg what the freaking problem is... and I USED TO DOWNLOD AT 5.3!!! What changed for Chrissakes? I had 50M, no I have 200. Tht's the only thing.
Re: speed limit changes
Same issue here. My laptop is running an older version, 0.7.20, and i get consistent 6+ MB/s speeds. My desktop was getting the same, but I had to reinstall Windows and so I upgraded to 1.1.0. Now I'm lucky to get 2 MB/s on my desktop while my laptop still happily gets 6+. Everything set up on both exactly the same. 30 connections. Obviously not downloading at the same time, etc.
Re: speed limit changes
We are looking into this problem.
As soon as we have the solution there will be a release 1.1.1

Re: speed limit changes
So glad I discovered this thread as I've been having the same issue since the update and it was driving me crazy.
Running on 80mbit fibre I used to download at about 7.9MB/s with 20 connections.
Checked my router and sync rate is exactly the same yet sab is only downloading at 5.3MB/s, changed connections from 20 to 10 and sab dropped to 3.1MB/s, changed from 10 to 8 and it dropped again to 2.7MB/s
Hopefully a solution will be provided soon but something is amiss with the update.
