> Yes, histograms can be extremely useful.
> The SmartShare applications use histograms for a variety of purposes, e.g.
> function profiling (like yours), number of packets per RX burst, number of
> packets per flow, and much more.
> The distribution index can be linear (like yours), log2, or - for higher
> resolution - floating point with 3 or 4 bits mantissa and 5 or more bits
> exponent.

> Please provide generic histograms as a proper library, not tied to a specific
> driver, and not specifically using "time" as parameter.
