> Avoid instanciation of MimeUtil for each Content object created
> ---------------------------------------------------------------
>
> Key: NUTCH-1652
> URL: https://issues.apache.org/jira/browse/NUTCH-1652
> Project: Nutch
> Issue Type: Improvement
> Affects Versions: 1.7
> Reporter: Julien Nioche
> Priority: Major
>
> Content objects instantiate and hold a MimeUtil in the constructor used by
> the HttpBase class. This is wasteful and unnecessarily slows down the
> creation of Content object as the MimeUtil creates a new Tika instance, reads
> from the configuration etc...
> Instead we could create a single instance of the MimeUtil class and pass it
> to the a new Content constructor
> {code}
> public Content(String url, String base, byte[] content, String contentType,
> Metadata metadata, MimeUtil mime)
> {code}
> and create a single instance of MimeUtil in HttpBase. We would also need to
> make sure that the synchronisation is handled properly in MimeUtil
> (especially for the calls to Tika) as the creation of the Content is done in
> a multithreaded environment.
