Day three of impressive and consistent performance on my AH account. Hope this is how it is going to be from now on.

Would be interesting when things MTN CDNs and Google Node are setup. Afriman? (you didn't think I wasn't going to ask you at least something, did you?)

We are not shaping uncapped accounts at the present time, so there should be little difference. However, remember that Capped accounts are always managed in a way that gives them best performance and lowest possible contention, while Uncapped accounts will also have QoS applied, if you are running multiple services. So if you are ONLY torrenting on Uncapped, you should get the best speed your line can provide. If you're also browsing, streaming, etc, then speeds will adjust accordingly for the best overall experience.

Once we implement shaping again, the experience may differ - but in general for now Uncapped should perform similarly to capped. With the extra capacity we have, there is very little contention on both capped and uncapped.

I have the impression that there is something strange with the QOS rules on uncapped. It seems that normal browsing and http downloads run 100% but the moment you start anything like torrents or nntp download, all protocols slow down to less than the total theoretical line speed. This is particularly noticeable if you speed limit your own downloads.

An example is I can get a >3mbps result on speediest, but start, say SABNZB but set it to max 50KBps and suddenly I can't get > 1mbps on speedtest. It's a if the whole connection is "punished" for the download?? Does this make sense to anyone? Is anyone getting the same result?

I have noticed the same thing over the past few years.... I'm not sure if it's an ISP problem, because I had the same issue when I was in the UK running 20Mb internet.... Had a torrent downloading at 20kb/s but when I was trying to stream HD when that torrent was on the DL it was impossible.... stop the torrent and *BAM* full line speed again! Same thing happens here in SA... I'm beginning to think it could be a windows issue!

It is because of TCP probably. Along with packet overheads and things like sliding windows protocol (to ensure in order delivery of packets) in TCP when dealing with slow SABNZB/downloads.

Maybe one of the smarterer guys can comment, because I have not looked at these things since my studies.
 
Delivery order isn't managed by receive/transmit windows, there is a tcp sequence number for that.
Slow performance on torrents could be because your router is battling with the large number of open connections?
 
I have now cancelled my Afrihost 4mb uncapped and changed it to Afrihost 4mb Business Uncapped

Yup same here, getting horrible speeds. Testing from the MTN network to the MTN server in Randburg on speedtest and getting 0.71mbps

Switch to my Telkom account test against the same server and I get 7.82mbps, but I guess we can still blame Telkom if that makes MTN feel better
 
Maximum all-torrents speed I'm getting at the moment, 70KiB/s

So annoying when I don't know what's causing the slowdown. Speedtests show everything's hunky-dory though :(
 
Have 4Mbs line and this is probably the best speed I have had in Cape Town in many years, Just hope that Afrihost can keep it going.
Ping 26Ms
Download Speed 4.01Mbps

Stuff is really loading fast and have even been able to stream HD 3D movie on my IPTV!
