I recently saw Latency Number Every Programmer Should Know and was having trouble getting my head around the scale, so I made this visualization to help me out.
I converted latency times to their equivalent light distances (how far light travels in that much time) and plotted those distances on a map to get a sense of the latency numbers in relation to each other.
The smallest few latency times are included here with their respective comparisons.
My company runs "speed interviewing" events over video chat to connect developers and companies for face-to-face conversations. If you're interested in latency and performance, we're hosting a web-event Tuesday and would love to have you participate: Hirelite.com.
