25000? That is quite low. You won't high get download speeds with that. It could very well be that 9MB/s = 90 Mbps is the max you can get with SABnzbd on the hardware.
(and, yes, it's annoying that we don't know a measurement to find the bottleneck)

See https://www.cpubenchmark.net/cpu.php?cp ... 40+1.99GHz how your Celeron J1900 compares to other CPU's.

What does your laptop say? If it has an Intel Core, it's probably at least 4-6 times faster, so a Pystone of 100.000+. Please post the same two SAB's CPU lines ... I'm really interested.

I booted up my old netbook:

Code: Select all

2016-02-15 20:51:48,450::DEBUG::[sabnzbdplus:1285] CPU Pystone available performance is 25009
2016-02-15 20:51:48,451::DEBUG::[sabnzbdplus:1290] CPU model name is Intel(R) Atom(TM) CPU N270   @ 1.60GHz

... so same CPU Pystone as you: 25000.

A download results in a 6.8 MB/s download

Code: Select all

2016-02-15 20:54:16,383::DEBUG::[bpsmeter:271] bps: 6506644.74381
2016-02-15 20:54:21,383::DEBUG::[bpsmeter:271] bps: 6731327.74764
2016-02-15 20:54:26,388::DEBUG::[bpsmeter:271] bps: 6765628.63645
2016-02-15 20:54:31,388::DEBUG::[bpsmeter:271] bps: 6854759.02489

So that looks the max for my system.

And it looks like 'top' is useful: still idle CPU percentage, but sabnzbdplus is at 99 %CPU.
(FWIW: start 'top', press '1' to see the load per CPU-Core)
