> Heya - so I'm working on a PR to make OpenNLP ME objects thread-safe.
> I'll provide the benchmarks in a few moments -
> # Old way — new ME instance per call (what module-chunker does today)
> # New way, instance-per-thread — one ME per thread, reused across calls
> # New way, shared single ME — one ME instance shared across all threads
> So this would mean you don't need to pool ME instances or worry about
> creating new ones every time.
> So far my initial tests show a 1.67x speedup in processing times for the
> tests I'm doing.. I'll have a better benchmark and create the PR soon.
