How can I test the bandwidth of my ADSL line?
Problem: I should have an ADSL line with 12Mb/sec download and 1Mb/sec upload speed.
Downstream: 12 Megabit/sec > 1.5Mbyte/sec > approx 1Mbyte/sec payload, the rest is in ATM protocol overhead.
After their test I started immediately to download from different sites to download big files, like Suse 10.2 beta and got a total speed of again 3Mb/sec.
I don't know about the country you live in, but here in Switzerland the ADSL connection speed is one thing, the uplink bandwidth (away from the provider) is quite another.
Obviously our testing is wrong! How can we really measure the bandwidth???
What exactly do you want to know: a) bandwidth from your site to your provider b) bandwidth from your site to an arbitrary other site c) something else (a) is easily done - your ADSL router will tell what the current connection speed is. (b) is a little more complex, but the number will vary a lot depending on time of day, other traffic, the other site etc etc. Per Jessen, Zurich -- http://www.spamchek.com/ - managed email security.
