Ah, sorry then i misunderstood the comment I'm not sure if it's with both RE2 or Rust, but some internal engines of Rust appear to allocate a fixed buffer that it constantly re-creates states into. I'm not really familiar with the eviction technique of RE2 but I've done a lot of benchmark comparisons. A good way to really stress test RE2 is large Unicode classes, \w and \d in RE2 are ascii-only, i've noticed Unicode (\p{class}) classes very drastically change the throughput of the engine. |
