Regexbench is a benchmacking tool for measuring matching throughput among various regex expression matching engines. Currently it supports rematch, hyperscan, pcre2, pcre2jit and re2.
regexbench is a commandline application. It is designed to work with libpcap. The typical usage is:
./regexbench myre.re mypcap.pcap
-
myre.re - regular expression rule file, the rule format is in pcre format '/abc/'.
-
mypcap.pcap - pcap file of packets to match
After match, regexbench will stop and display statistics, it will also write the result to a json file (default output.json).
regexbench supports the following options:
-
-h help info.
-
-e engine to perform the matching. Currently it supports rematch, hyperscan, pcre2, pcre2jit, re2.
-
-r repeat pcap multiple times.
-
-c concatnate pcre2 rules. To turn on, one should specify -e pcre2 -c 1 or -e pcre2jit -c 1, default off.
-
-o output json file, default (output.json)
-
-s rematch session mode. To turn on, one should specify -e rematch -s 1, default off.
