Hi all, I have written the Aho Corasick algorithm in C (corresponding to AC_FULL option in snort) as a part of my thesis. While running the Aho Corasick Algorithm with the snort rule set I noticed that while the Data structure (the tree like structure of the algo) consumes 53 MB the storage for the matched rules is 800 MB. Is this really the case or have I missed something. I tried running the acsmx.c file in the snort distribution with the snort rule set but the program is getting killed. Also in order to build the automaton I used the characters following the content keyword in the rules.
