Hey guys, hopefully someone can shed some insight into my problem. Over the last few days I've done quite a bit of troubleshooting so I'll try and be as clear as possible:
OS: OSX 10.7.2
Skin (if applicable): default
Firewall Software: none
Are you using IPV6? no
Is the issue reproducible? yes
Here's the issue. About 4 days ago I started using sabnzbd and usenet. Everything was great, I was getting 1.5-2MB/s download speeds. Speedtest.net showed that my comcast speed was getting 16-22mb/s download and 2-3mb/s upload. Perfect.
~150gb of downloads later and things start to crash and burn. I noticed that my internet connection had slowed to a crawl (all browsing, downloading, etc). I checked sabnzbd and found that it was running at about 100-200KB/s downloads. So I restarted the system, tried again. Now every time I run sabnzbd on my mac mini server the entire network slows to a crawl. web pages hardly load, downloads crawl, speedtest shows about 1-2mb/s download speeds. WTF
I have tried changing the number of connections from my usenet host (from 20, to 13). I have tried changing the cache settings down to 120M. I have tried limiting bandwidth to 1000KB/s download. I have tried reinstalling the app. I have tried resetting my router and modem. I have run a Glasnost test which said "my ISP is not shaping or throttling my connection". I have checked comcast and I'm still at 75% of their 250GB limit. I have cleared my queue and made sure my files are under 10gb (I only have 1 file in my queue at the moment).
I have done so much testing, and narrowed it down to something with sabnzbd specifically. Torrents run fine, other downloads run fine. As soon as you run sabnzbd and start a download the network slows down like crazy and stays limited to 100-200KB/s if I'm lucky. Sometimes I'll catch it at like 79KB/s. This is the whole reason I started using usenet and sabnzbd. What should I do next? I have no idea where to go, or how to fix this issue. I can't use it if I'm only getting kb/s download speeds
Any help is appreciated
