--- Comment #1 from Stephan Bergmann <[email protected]> --- LibreOffice's document type detection code is notoriously slow, trying lots of filters one by one until it finds a good match, and seeking and reading the same data over and over again from the given input stream. So, if that stream is only made available across URP, this can easily cause lots of delay, esp. if the stream's data is in a "bogus" format for which no matching filter can be found (so the search needs to go through all of them). That said, if you say things were considerably faster with an old OpenOffice.org version (which exactly was that?), it might be a performance regression in the rewritten binary URP bridge hinted at <https://issues.apache.org/ooo/show_bug.cgi?id=116038#c14> "rewrite binary URP bridge." -- You are receiving this mail because: You are the assignee for the bug.
