C API

Benchmarks

This page provides guidance figures for detection speeds, memory usage and startup times for Pattern and Hash algorithms. For more information check out the how device detection works page.

Results stated are detections per core on a quad core i7 2.2GHz using the PerfPat and PerfTrie (for Hash) tools included in the C project.

Pattern Benchmarks

Below is a table of performance metrics relating to the C Pattern API. It shows the detection speed for a single request for each data set and where applicable also the mode of operation used.
