>             Project: Tika
>          Issue Type: Bug
>    Affects Versions: 1.16
>            Reporter: Eamonn Saunders
>             Fix For: 1.17

> Parsing of the attached urlclassifier3.sqlite database is approximately 5 times slower in Tika 1.16 than it was in 1.14.
> I've performed some profiling and it appears as though the problem lies in the number of times a new TikaConfig instance gets created. See attached screenshot
> I notice that EmbeddedDocumentUtil has 2 methods to get a TikaConfig, one of which caches the config instance. Are both methods needed? Why does EmbeddedDocumentUtil.getExtension() use the version that doesn't cache the config?
