WebSep 4, 2024 · Before doing this match, I ran both RE2 and HyperScan regex's against a very long string in order to warm up the DFA state tables (in the case of RE2, this resulted in a OOM causing the system to revert to NFA mode). In my benchmark, RE2 took 7 seconds and Hyperscan took 18 seconds. WebFirstly, Hyperscan offers a performance advantage for sets of patterns drawn from the snort_pcres regex set against web traffic. RE2::Set offers comparable performance for some single regex patterns, but drops to running at its baseline performance of 3.5-4.5 Gbps for sets larger than one pattern. As the regex set size increases, RE2::Set ...
