I have been re-reading Tom Limoncelli’s et al. The Practice of Cloud System Administration book (which is great and is well worth reading even 5 years after it has been published) and it has this wonderful reference table called Latency Numbers Every Engineer/Programmer Should Know. This table was popularized by Jeff Dean, and originally presented by Peter Norvig. I find it handy and wanted to copy it here, on my blog, but then realized it’s almost a decade old as the data was from 2012.
