[jira] [Created] (TIKA-2511) Slowness parsing SQLite database file

Eamonn Saunders created TIKA-2511:
-------------------------------------

             Summary: Slowness parsing SQLite database file
                 Key: TIKA-2511
                 URL: https://issues.apache.org/jira/browse/TIKA-2511
             Project: Tika
          Issue Type: Bug
    Affects Versions: 1.16
            Reporter: Eamonn Saunders


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?
