8 months ago Very interesting! If I understand correctly, this is results of benchmarks of crates themselves, you didn't integrate stringzilla to quick-xml, right? I'm always open in performance improvements so if you will you can create a PR with a replacement so everyone can experiment with such change. Note, however, that these results probably from searching small patterns in long strings. XML usually has a different access pattern -- many searches of small patterns in small strings. As you can see from quick-xml self benchmarks, the maybe_xml is even faster than quick-xml in most cases, although it does not use any SIMD libs. quick-xml wins only on very long XMLs (several megabytes) which, I think, usually a rare case.

Came across a benchmarking comparison between the two.
Notably the results:
memchrstringzillamemchrstringzillaIts noted that that rust crate doesn't cover the full
c++api, but that it is planned to do so eventually. In the interest of performance, I thought I would share the benchmark results so informed exploring can be done if desired, if the potential gains match up with any wins for one crate or the other.
