[jira] [Comment Edited] (TIKA-3431) Using any setting other than AUTO or NO_OCR for X-Tika-PDFOcrStrategy causes remarkable performance loss

    [ https://issues.apache.org/jira/browse/TIKA-3431?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17355463#comment-17355463 ]

----------------------------------------------------------------

Rendering PDFs is slow (especially with 300dpi), and OCR is slow too. The rendering improves from time to time, but this is like a few percent, and only for some files. On windows, set your energy settings to ultimate speed. (There's probably a similar setting on other OS)

> When processing PDF document to the local Tika server using PUT request to endpoint [http://localhost:9998/tika.]  If the PDFOcrStrategy is set to anything other than AUTO or NO_OCR, this causes extreme slowdown in processing of the PDF file.  
>  
> It doesn't matter if the PDF document has inline images or not, the slowdown happens regardless.
