Ok, I've been test driving the 4Mbps trial for a few days, and when I read the title, I was wondering if it meant that the trial accounts are prioritized, but the actual accounts aren't. Apparently the they are provisioned exactly the same, so that makes me feel better about it.
The trial products are provisioned in the same configuration as our billable products, to ensure that the experience you have on one of our trial products gives you an accurate view of what your service will be like when you sign up with MWEB
Anyway, I did a few speed and ping tests on my WA account, then switched to the MWeb trial and did some more, and I've played a few hours of Battlefield on the XBox to see how it goes. I've also downloaded a few games to the XBox and PS3, and so far so good.
I noticed that local connections were faster and had much better ping on MWeb than on WA, but WA was a little better on international connections than MWeb. Playing BF, where I usually see 4 bar connections to the EU servers with WA, I saw 3 bar connections with MWeb, but I think it's because I was just under 200ms ping on WA, and just over 200ms ping on MWeb. I didn't have any problems with lag though, so it seems fine, I think it's just a few ms difference really.
I also watched some YouTube through the XBox, and it all ran lekker without buffering or anything.
If I keep running out of bandwidth, I might just change over to MWeb
