Super duper slow downloading speeds

[ki99]

Hello all,

Thanks for reading this, hopefully it will be an easy fix.

I have a HP Thin Client T5720:
AMD Athlon 1ghz
496MB Ram

It does not have a hard drive so I have installed Sabnzbd on a usb flash drive.

The problem I'm having is my download speeds are maxing out at around 10kb/s with sabnzbd, I have it set at 10 connections to my server and they are all connecting fine but the speed remains slow, I have checked the log and can't see anything in the way of an error.

I have also installed alt binz and this is downloading at the expected speed of around 2500kb/s  so I'm fairly sure the problem is with sabnzbd.

I'm using hitnews.eu and I am connecting via ssl if that helps?

The solution to this is beyond me so please help me if you can!

10 kb/s usually means that SABnzbd is getting nothing but "don't have article" messages from the server.
You're sure the NZB is OK?
Is anything actually downloading?

Thanks for the  quick reply, I have just tried a NZB that I know works and the speeds are fluctuating from 6-12kb/s. I have checked the download folder and the PAR2 files are present so I'm guessing it is downloading just very slow for some reason?

It's likely that the USB stick slows everything down.
By default, SABnzbd doesn't use an article cache, which means
that each article requires three disk accesses.
Solve this by setting an ample article cache in Config->General.
100M is usually a good value.
Keep in mind that on constrained hardware (which this certainly is)
SABnzbd's performance will never match that of altbinz.

Thank you again for the reply, I tried your suggestion but it remained the same. So I spent a bit more time fiddling around and tried the non SSL server and it seems to work better on that, the speed is still all over the place but it is more what it should be, any ideas why it is not working on SSL? I tried both ports but was still 10kb/s

Thanks

Which OS do you use?
We depend on the quality of the OpenSSL libraries
and SSL has a performance penalty.
