Thought I'd post some more feedback on unshaped ADSL for those interested. As you know, I posted some initial results, fights with TELKOM etc, when I first signed up for the service (http://www.myadsl.co.za/forum/topic.asp?TOPIC_ID=3172&whichpage=1).
About a month later, and after the initial disappointment, <b>apart from the costs</b>, I have to say that the service has been consistently reliable:
1. <b>Latency</b> is consistently better than shaped ADSL. Local pings (from Cape Town) to Jhb based servers are consistently in the high 20ms to low 30ms range - identical to shaped ADSL.
International latency is where the difference really kicks in - I ping all European servers in about the 250ms range. During peak hours in the middle of the day it's slightly higher by about 30-40ms. To the USA results seem to vary depending on whether I'm connecting to East Coast or West Coast servers. East coast servers are in about the 280ms range, while West Coast at about the 330ms range.
2. <b>Peer to peer</b> I'm not a heavy user of p2p applications, but I have done some random downloads now and again - and on each occasion downloads maxed out at about 450kbps. Again, this was tried at random times of the day and night, and I seemed to get identical performance. I have also tested Bit-torrent downloads over the last week, and that also maxed out consistently at 450kbps.
3. <b>Web browsing</b> can't notice any discernable difference other than during peak hours in the middle of the day when the unshaped account is noticably quicker. In the evenings, performance appears identical.
Last, but not least, I made some cryptic hints about this in other posts for fear of Telkom picking this up, but what the hell... I have no real need for it so if things change tomorrow at least I'll know how closely they monitor these forums [
]. My i.p address has been static since they put me on the correct unshaped i.p. range about 2 days after initial sign up. Their may well be a logical explanation for this e.g. maybe there are so few unshaped ADSL users ?. I have disconnected, reconnected, reset my modem etc - but the address has remained consistent. I check it every day, and after every disconnection and it hasn't changed at all - yet!
I have not needed to use my ISDN line at all since being on the unshaped service, and my total bandidth usage as at today is 2.8 gigs. As you may know, the unshaped account has a 4 gig cap, so I am still comfortably within the limit without sacrificing any of my usage habits. The downside is that you are <b>completely disconnected</b> from the network when you cross the 4 gig limit. I have no plans to test that yet [}
], but do have access to a family member's shaped ADSL account should that happen [
