Michael McCandless created LUCENE-9986:
------------------------------------------
Summary: Create a simple "real world" regexp benchmark
Key: LUCENE-9986
URL: https://issues.apache.org/jira/browse/LUCENE-9986
Project: Lucene - Core
Issue Type: Improvement
Reporter: Michael McCandless
For issues like LUCENE-9983, where we are struggling to decide which low-level
optimizations to make for our (complicated!) {{determinize}} method, it would
really help to have a large, real-world corpus of regexps to evaluate
performance metrics of our automata operations, like CPU and HEAP required to
parse the regexp and determinize.
Does anyone know of such an existing, hopefully compatibly licensed, corpus?
Probably we would add these benchmarks to {{luceneutil}}.
