Slow download speeds on Mountain Lion, other clients OK

[jcfp]

• NZBVortez: 400 KB/s
• SABNZB 0.7.6.beta1: 400 KB/s
• SABNZB 0.7.5: 400 KB/s
• Transmission BT: 400 KB/s

but my SpeedTest results and direct downloads still clock in at 3Mb/s

speedtest.net reports in megabits, 3.00 Mbit/s = 3000000 bits/s = 375000 bytes/s = 366.2 kBytes/s. Pretty close to the 400 kBytes/s sab and others indicate, and also a number not unlikely to be "slower than 72% of us connections" as the speedtest image puts it. Looks like you got yourself a speed limit on your connection somehow, starting in week 43.

Hey everybody,

I'm new to the forums, figured I'd sign up to add to this thread...

I am experiencing similar issues in ML. Ever since moving from my windows setup of SABnzbd (Win 7 x64) to Mountain Lion (OSX 10.8.2) I've noticed that my downloads start out at max (2.0 MB/s) but always work their way down to about 800 KB/s.

I've tried lots of tests to try to determine what the issue is but can't figure it out for the life of me. I know its not my router as I've tried it without the router (direct connection to the internet) and the same thing happens. Also tried it without SSL but the same thing occurs. I use UsenetServer btw. I've tried changing SSL port numbers, same thing still happens. Tried decreasing my max connections from 20, same thing happens.

More info:

SABnzbd Version: 0.7.9
ISP: Eastlink
Usenet Provider: secure.Usenetserver.com:563 (SSL) - Max connections = 20
OS: OSX 10.8.2

Any ideas would be much appreciated! and pls let me know if you need more info!

Thanks!

Rather puzzling, since SABnzbd is primarily developed on Mountain Lion.
Of course there are many factors involved.
Do you happen to use a software firewall (like Little Snitch) on your system?

[colp]

nah, I'm new to the wonderful world of Mac but the only firewall I have enabled is the OSX built-in one, however disabling this also produces the same results.

Cant be ISP throttling either...just restarted SABnzbd and its been steady at 2.3 MBps for atleast 10 mins now. I've seen this happen before but it will eventually drop down to 800 KB/s.

[colp]

Also verified with my ISP (Eastlink) that they only throttle on upload for file sharing (p2p), so the ISP isn't the issue.

Are you using wired or wireless?
Wireless is a challenge for sustained downloading.

[colp]

Wired.

OK, so unless you are using IPv6, I'm out of suggestions

[colp]

I just set IPv6 to locallink only, not sure if that will make a difference but i'm willing to try anything

Thanks for the help!

[shypike]

One desperate attempt: set ipv6_servers in Config->Special to 0.
Then restart.

Doesn't look like that fixed it either...it might just be where I am downloading them from, when i get home I'll double check but pretty sure I've seen some EU servers instead of US servers in my connections list, that's most likely the cause of it I'm thinking.
