Here’s something for the gearheads.
At home, we’ve got a permanent Comhem broadband fiber connection offering 10 Mb/s down & up. Its actual performance is about 9 down and 10 up, which is OK. I like to have a swift uplink since I send a lot of large files and keep my data on a DAV server for easy access from the four computers I work with. This, to the majority who have never heard of a DAV server, means that with a slow uplink, it would take a lot of time for me to save my work when I press CTRL-S.
(A funny thing about permanent internet cabling in Swedish apartment houses is that its endpoint is usually installed right inside the front door. This is of course a sign of how new this utility is: nobody would accept to have their electricity, their phone line, their water pipe, their drainpipe or their central heating ending at the front door.)
Glocalnet recently offered me an ADSL connection that would be cheaper than the fiber connection and give us “up to 24″ Mb/s down and 1 up. ADSL is a temperamental technology as it relies on the copper lines of the old phone network. Its performance varies both with the distance from your socket to the station and with the length of the cable from the socket to the modem! This means that it’s basically impossible for an ISP to predict what kind of performance you’re going to get. Still, I hoped I might get a doubled download speed (18 Mb/s) for less than I was paying for fiber, so I ordered the service.
Sadly, I got unimpressive bandwidth. Using Bredbandskollen to check, I found that even with a really short phone cable I only got 12 down and 1 up. I’d rather keep paying a bit more and keep my fast uplink. So now I need to extricate myself from the service. I guess nobody actually gets 24 Mb/s from an ADSL connection.
