Unusual Download speed

[ecoh419]

Hello all.....

So I recently switched my connection speed with my ISP from 29Mb/s to 25 Mb/s (drop in speed is due to my isp's packages). Any way with my 29Mb/s connection I was getting an average download speed in SAB of 3.4MB/s, which was great. Now that I've switched to 25Mb/s I'm getting 1.4 MB/s. Should I not be getting roughly 3.1MB/s?

Not sure why.... my connection to my hosting is through SSL. I started using a VPN Service after this problem presented itself thinking about throttling. 1.4MB/s speed is constant with the vpn service on and off. I've confirmed with my isp as well as speedtest.net that my connection speed is intact 25Mb/s.

I'm running SAB 0.7.7

Have you tried other software that produces a consistently high download rate?
What are the results?
Did you read the ISP's fine print?

It's well documented that MY ISP throttles bittorrent traffic. However, I did not change ISP's I just changed plans so if there is throttling in play, would it not have been happening while my connection was at 29Mb/s? I'm using steam as an example and it is currently capped at 1.4MB/s Just like SAB so obviously there is a constant.

Hardware hasn't changed. Why would my ISP throttle steam? I thought traffic shaping is done by monitoring ports known for bit torrent and then throttling.

I'm also using SSL for my usnet hosting should that no negate my ISP's ability to throttle?

Thinking it was my router (d-link DIR-655) I connected directly to my modem and had the same speed of 1.4MB/s

Doesn't ring a bell.
I'd still say try another piece of software to download something really big
and see what result you get. Downloading a 5G Ubuntu ISO with your web browser should
give you an idea.

Downloaded Ubuntu like you suggested and I get 1.6 MB/s

It does look like a limitation caused by your provider.
Always hard to tell, because there are few sites that always deliver great speeds.
If you still think it's SABnzbd, you should try an alternative Usenet client.

I though using SSL in sab negates the isp's abilities to throttle? Also I'm behind a vpn

Not at all: with NNTP-SSL / NNTPS, an ISP can still throttle: based on IP-address of the newsserver, or on the NNTPS port.

The goal of NNTPS is that an ISP (or system administrator or government or other eavesdropper) can't see the *content* of your communication. It's still clear you're using Usenet.

Also I'm behind a vpn

Are you? Have you tested the web browser downloadspeed with an Ubuntu ISO both with and without VPN? If the speed is 1.6 Mbps in both cases, and do you don't like that, talk to your ISP. It's not SAB or Usenet related.

downloaded ubuntu ISO with my vpn disconnected. same results I get down to 1.6MB/s interestingly enough though the speed starts at 2.8MB/s then starts to drop 5-10 seconds in to the download to 1.6MB/s. I've noticed the same behavior in SAB with the vpn on and off.

So its not SAB, what could cause a connection to do that? Would an ISP throttle every aspect of activity?
