very slow downloads

Hello,

I'm running sabnzbdplus 0.4.9 on Ubuntu Jaunty.  My ISP is dslextreme, which I believe uses supernews for their usenet access, throttles at 2 connections with something like 45KB/s max per connection, and no SSL.

I'm trying to switch from hellanzb.  With hellanzb, I'm getting the expected max d/l speeds of around 90KB/s sustained.  Sabnzb+ has been going around 0.5 - 6.0KB/s.  I have the throttling value set to zero for unlimited.  I've tried multiple NZBs.

The error logs are empty and don't see anything obvious (to me) in the debug logs.

Any ideas?

Thanks!

Have you tried more connections per server (if allowed)?
Did you try to download the same NZB file(s)?

Hi shypike,

Thanks for the response!

Yes.  I can only do 2 connections max with my ISP, so it's set to that.  But the exact same setup -- same server, same connections, same NZB -- running under hellanzb goes at max speed.

I'm also starting to see these warnings fairly regularly:

Code: Select all

2009-08-17 08:49:51,576 WARNING [downloader] Thread [email protected]:119: timed out
It also seems like once it gets a few timeouts it actually stops downloading entirely and sits at 0.0KB/s until I Pause/Resume all.  I think the connection to my news server has always been a little flaky but hellanzb has always been rock solid about keeping things moving as best it can.

I'd really like to switch to sabnzbd+ (great rss features!), but this is a deal breaker at the moment and I'm not sure how to investigate further.

Thanks.

I really have no idea.
Usenet communication is quite a simple protocol, there's not much that can go wrong.
Rock-solid is the general impression SABnzbd gives to people,
except for some rare complaints like your's.
I assume you set the server timeout to some decent value (most providers reccommend 60-120 seconds).

The timeout warnings as such are nothing to worry about.
This is quite normal (also with hellanzb), but we just show it too prominently.

You could sign-up for the Release test program (see Beta board) and get access to the pre-releases of 0.5.0.
Just to see if it makes a difference.
