Performance Metrics using wget

I am looking for a way to measure performance metrics of streaming audio/video from a contecnt server, e.g. YouTube for example. Im keen to see if I can look at duration it took for contecnt to download.
I know from the output of wget's log file you can see duration a url is downloaded in.
However I need to get the duration it takes for the streaming content.
Thanks

It would scale from a few... (0 Replies)
