Download speed problem [Raspi]

I got an upgrade to my internet speed, so from 1 Mbit connection, I switched to 10 Mbit, quite good change for me. I am using sabnzbd on rasperrypi, which was working great with 1 mbit connection, topping to 120 kb/sec download speeds.

After I got an speed upgrade, I can't have a stable speed connection, my max speed goes to 400 kb/sec (instead of 1.1 Mb/sec) then drops to 100 s, then goes back to 360 kb/sec , so it's not stable. And I started to get high amount of load on rasp pi, like 6 or 7 .

I tried sab+ on windows desktop and it easily goes up to 1.1 Mb/sec and maxes out my connection speed which is quite good. But the point I can't really understand is, why I can't get same speed on rasp pi device? Is it because of high load issues on rasp pi, or is there another cause for this issue?

Yes, the Raspi's CPU (and RAM) is the bottleneck.

so is there a way to optimize sab+ for rasp? When I check from some mobile app via sab+ api, I can see speeds up to 810 kb/sec but that's not for forever also.

My usual saying: if you need high download speeds on low-spec hardware (low CPU and/or low RAM), you might be better off with nzbget instead of sabnzbd. NZBget offers less functionality, so you have to decide for yourself.
