There are some AC/BM discussion in the archive, see for example: http://lurker.clamav.net/message/20100426.103047.eb6fd9d0.en.html http://lurker.clamav.net/message/20100427.131931.b705e603.en.html http://lurker.clamav.net/message/20081204.212941.c9fa45c2.en.html You can use DevACOnly to use only the AC algorithm for everything (there is no equivalent for BM), Other than that you can use tools such as 'oprofile', or 'perf record / perf report' to see how much time is spent in functions from matcher-ac.c and how much time in those from matcher-bm.c. Also note that there is the prefiltering step too, if you want to measure just the AC/BM performance, you should disable that (although you'll loose performance by doing so). What are your research project's goals?
