Slow downloads after moving ISP

[ribbox]

HI,

I have moved from Optus to Superloop (Australia based) and found the my downloads have dropped from 12MB/s to 500KB/s - 1000KB/s.

My connection now is fiber to the premises limited to 1000Mb/s the old connection was 100Mb/s.

I have no problems with any other activity of the internet just slow downloads via SABnzbd.

My setup is HP computer running docker and SABnzdb connected to the Host network. The new ISP provides both IPv4 and IPv6. Disabling IPv6 at the modem changed from 500 to 1000 KB/s, SABnzbd version: 4.2.3

before the upgrade of ISP I had the likes of

There has been no change in the config of SABnzbd.

** Edited to add that I use 2 news providers, both have the same download speeds

That's bad.

What is your ping time to the newsservers?

Not good either if you have a 1000 Mbps connection. On the same system, what is your speed on https://fast.com/ ? And on another PC on your LAN?

Hi, on the speed check site 180 Mbps

Then contact your ISP: you pay for 1000 Mbps, so then 180 Mbps is much too low. It might be your LAN, but let your ISP determine it.

ping times: what do you get with news.newsdemon.com ? And what if you fill that out in SABnzbd? SAB will find the quickest servers.

From my SAB debug logging:

I think I have found the issue, the new modem only has 2 ports, so I used a switch that I had used before that supports 10/100/1000 the OS was reporting a connection of 1000, so did not think that was the problem. I swapped out the switch with a newer on that says "gigabit" and that works fine.

I have ordered a newer switch, that 2.5G so that should remove any bottle neck in the LAN.

OK, good find. Maybe the in-between caused slowness due to ... packetloss?

And SABnzbd news download now also back to old levels (when directly connected)?
