Tim Allison commented on TIKA-2276:
-----------------------------------
I found a few places where we're creating new parsers for embedded parts (e.g.
RTF/HTML in OutlookParser). By reusing the parser sent in via the
ParseContext, the time to parse went to 4 seconds from ~68 seconds for
"testChm2.chm".
> Try to be more parsimonious creating TikaConfigs and ParseContexts

> URL: https://issues.apache.org/jira/browse/TIKA-2276
> Project: Tika
> Issue Type: Improvement
> Reporter: Tim Allison

> Fix For: 2.0, 1.15
>
>
> If we run the AutoDetectParser() against the files in our unit tests (around
> 600 files*), there are 701 new instantiations of TikaConfig. The time is
> around 20 seconds. If we modify AutoDetectParser to pass its TikaConfig via
> the ParseContext if one isn't already specified, that drops to 234
> instantiations, and parse time goes to ~17 seconds.
> Let's make this simple change and look for other areas to decrease the number
> of times our parsers are creating a new TikaConfig.
> *Note I did not include the testCHM2.chm monster in these runs.
