Comment 2 Jean-Baptiste Faure 2018-01-02 18:11:15 UTC
The problem seems to comes from the repeated svg image. Interpreting svg language is always CPU consuming. You should convert this image in png format. I did that by compressing the first svg image (right click then compress) then copying the resulting png image in place of others. The new file is only 40 kB and is opened in only 1 second.

That said, before opening a bug report, you should have ask for help on users mailing list.

Closing as NotABug. Feel free to reopen if you disagree.

Best regards. JBF

Thank you for the comments, and while it has resolved the problem with this file, I still believe this is not acceptable performance. There are 12 copies of an identical SVG in the sample file, and 3 minutes on a reasonably fast processor (Intel i5) still appears to me to be poor. 

At the very least, Libreoffice should be displaying progress while it processes the images - and I believe this behaviour would also occur in Impress as well as Draw (and probably anywhere else where SVG files could be processed).

I've reopened the bug, but reduced its importance to "minor".

Probably bug 83426 or bug 101682 (full list of known issues: https://bugs.documentfoundation.org/showdependencytree.cgi?id=99825&hide_resolved=1)
