PPTX attachment 162028 [details] from bug 128871 loads very slow in Windows from LO 6.3 up to 7.2+. Looks like regression.

Hi Aron, could you bisect this please, I think you do it in Win.
This started with the following commit, bibisected using bibisect-win32-6.3. Considering this came with an added feature, I'd say it isn't actually a regression. https://cgit.freedesktop.org/libreoffice/core/commit/?id=8a1321362a0229a25869e4e3d0422a5a51c5b5be author Mark Hung <marklh9@gmail.com> 2019-01-20 20:33:26 +0800 committer Mark Hung <marklh9@gmail.com> 2019-02-04 01:03:00 +0100 tdf#44223 oox: import embedded media stream.

Testing with just master is inconclusive. One should test with version before regression to compare.
For me the times when opening the PPSX from Impress are: - ~40s in a recent 7.3 daily build and in 7.0.0.3, - ~5s in 6.2.0.3. We should probably aim for a sub-10s load time.
