Anecdotally, I had an interview years ago for a small-ish futures trading company based in London. The interviewer had to pause the interview part way through whilst he investigated a 10ms latency spike that the traders were noticing on a short point-to-point fiber link to the London Stock Exchange. He commented that the traders were far better at 'feeling' when an connection was showing even a trace of lag compared to normal than anything he'd set up by way of monitoring (not sure how good his monitoring was, though.)
This was my experience in a callcenter as well; network type problem reports always came in from the floor managers before Nagios came forth with an opinion.
When I used to run an ISP network, our NOC always talked about "that porn guy" who would call the *exact* *momment* the NNTP server had any type of stutter... I guess there's always a canary for the coal mine -- eh?
