Speeds throttle?

Post by Vectraat »

While I doubt this is being caused by SABnzbd, I thought I'd ask anyway.

-I've always had reasonable download speeds with SAB that are consistent, but I've updated SAB few times recently and now for the past month my speeds have been poor. They'll start out high but very quickly throttle down.

-I've run several speedtests and I'm always getting a higher download speed than what I pay for and my ISP never throttles.

-I've restarted my modem/router and fiber box. Rebooted my computer. I haven't changed any settings on my modem/router in a year+

-I ran the SABnzbd setup wizard again, tried different hosts and ports. I set the connections to what they normally are. Nothing changes, still poor download speeds. It could be coincidence but like I said, I felt that I noticed this issue at some point after updating SAB.

Any idea if this could be SAB or is this throttled behavior likely being caused by something else?

Without details (including Wrench rwport) it's guessing

Ok, which details would you like, and what's "Wrench rwport" ?

I'm thinking this might be an IPv6 issue. I guess I can go: Special --> uncheck ipv6_servers.

Edit: Nah that didn't fix it.

In SABnzbd's upper right corner, click on the wrench symbol ("Status and interface options"), then click on first tab Status, and there click on the Refresh Arrow/Circle. Post the values of the lower part here.

First things first: make sure you get 35 MB/s at Internet Bandwidth. Nothing to do with SABnzbd nor newsservers settings.
