script to measure download speeds of different servers

You can write this in either a Linux Shell Script, Perl, or PHP. I need a script to download a static file from several different servers and measure the download speed. The script should do the following: 1) read a config file in this format: (this must be in a separate file than the script itself) # specify an arbitrary number of friendly_name and IP pairs. The exact data structure you use doesn't matter. friendly_names_and_ips = [ ["name1", "[login to view URL]"], ["name2", "[login to view URL]"] ] # this URL is the same for all IPs url = "/some_path/[login to view URL]" 2) for each element in friendly_names_and_ips: (in sequence, not in parallel) - wget "http://$ip:80$url" - determine the average download speed in KB/s. For example, "wget [login to view URL]" shows: 2012-08-01 10:57:36 (91.0 KB/s) - `index.html.1' saved [13285] ---> save 91.0 3) output results in CSV format with these columns, one row per server: - current datetime (when printing the output, not when the test was run, might might have been a few seconds earlier, but that's OK) - friendly_name - IP - url - download_speed_in_kb_s Don't write the column names. Only write the data values. When I run this script, its only output should be something like this: 2012-08-01 12:12:12,name1,[login to view URL],/some_path/[login to view URL],91.0 2012-08-01 12:12:12,name2,[login to view URL],/some_path/[login to view URL],82.0 I'd like this completed within 24 hours of project start. It needs to run on Ubuntu 10.04 LTS. Test it on your own machine, I won't provide a test environment. Thank you for your time, I look forward to seeing your bid!
