Slow start at begining of download 1.1.0RC1

[jdloaner]

I have been running SAB for many years (up through version 0.71 i think) however tonight I built a new Ubuntu server and 1.1.0 now have installed. I notice when I add an NZB the first 10 seconds or so the download speed stalls at ~700K and then spikes up to the normal 25-30MB. Has anyone else seen this? I tried with several different NZBs and then loaded those same ones on my 0.7 install and they started instantly, as usual.

This might be due to the new way we make connections, where we ask the DNS for all the IP-addresses (usually a newsserver has multiple per hostname) and then check whichever is fastest.
Maybe you can try and disable it in Config > Switches? It's the 'Server load-balancing' feature.

This might be due to the new way we make connections, where we ask the DNS for all the IP-addresses (usually a newsserver has multiple per hostname) and then check whichever is fastest.

I would be very surprised if that would be the cause. The new feature (happy eyeballs) is meant to avoid lookup/connection delays.

So @jdloaner

Set SABnzbd's Log to +Debug, run a download, and check /.sabnzbd/logs/sabnzbd.log for lines with "happyeyeballs".

Note: you will only see lines if your newsserver has more than one IPv4/IPv6 address.

Code: Select all
