Very Slow Download Speed From Marketplace

I would go into your router as an admin and use port forward. Here are the ports

Xbox Live requires the following ports to be open:

Port 88 (UDP)

Port 3074 (UDP and TCP)

Port 53 (UDP and TCP)

Port 80 (TCP)

How to set up port forwarding

You may find information how to open ports on your router at the Port Forward website. Go to the Port Forwarding Guides for Xbox Live 360 page to find instructions for your router.

If your router is not listed on the Port Forward website, contact your Internet service provider or router manufacturer for help with opening network ports.

Tip The Port Forward website is available only in English. To translate the site, copy and paste the URL (www.portforward.com) into a translation tool, such as Bing Translator.

For more help with opening network ports, contact whoever provides support for your router, such as your Internet service provider or router manufacturer.

Yes, any games or apps downloaded through the store are capped at the same speed showing in the speed test using Edge.

While I also get less than optimal speeds when I speed test through Edge, my Marketplace downloads are consistent with my internet speed (granted, I "only" have 100Mbit, and due to the distance from the DSLAM I "only" get 70-80Mbit download speed).

So are the actual marketplace downloads when you download a game or an app equally slow?

I have this too, I'm downloading GTA San Andreas an I'm at 16% in 3 hours I think it's because I'm downloading it to a hard drive. But when I try to change the storage unit it won't work.

King John I noticed similar speed issues today when downloading some of the newier DLC for Borderlands 2 (Psycho Bandit, Compatibility Pack & Assault on Dragon Keep). I have a 50Mbp/s down & 5Mbp/s up connection & a TP-Link Gigabit router with LAN connections
to my PC as well as XBOX360. All ports are opened properly, I have my Xbox360 in the DMZ & no other downloads/uploads taking place. I did separate tests on my PC & XBOX360 from the site
http://SpeedOf.Me as that does speed test through HTML5 so you can use it on the XBOX360 IE verison. My PC speed results were 56.9Mb/s (d/l) & 5.38Mb/s (u/l) now my XBOX360 speed results were 1.45Mb/s (d/l) &
3.18Mb/s(u/l). I tested my XBOX360 results again & they were 1.51Mb/s (d/l) & 3.21Mb/s (u/l). THIS IS ABSOLUTELY HORRIBLE as I know I was getting better speeds on LIVE when I had my 15Mbp/s (d/l) & 1.5Mbp/s (u/l) though I never knew about the SpeedOf.Me
site to do testing prior to upgrading. How I know though is my friend had a 50Mbp/s connection with Comcast & when we would d/l DLC I would always d/l faster than him. Hope this helps & MICROSOFT PLEASE FIX THIS AS ITS HORRIBLE PAYING FOR A GOLD MEMBERSHIP
BUT BEING SEVERELY RESTRICTED ON BANDWIDTH THROUGH LIVE!!!
