Hi,

We took a look at the file and we can see why it takes so long -- it's the
background gradient you have on each slide.

Sometimes a very smooth gradient will greatly increase the file size (and
processing time) for each slide.

The solution is to remove the background gradient for each slide. Once you
do that, you'll find that the presentation will convert very quickly.

I case if help, The reason for slow uploading of this pdf is not because of
background gradients. this was because of the pdf maker (or meybe the pdf
options for making pdf).
I Opened this pdf in Chrome Browser and print it again using chrome's save
as pdf then pdf uploaded and converted fastly in bigbluebutton.
when watching the pdf properties in acrobat reader the differences that I
see was as follow:the first picture is the orginal pdf's properties. the
second picture is the pdf that printed again using chrome browser.

We just tried Страхование 4.pptx and it converted reasonably quickly on a
0.9 server. Can you try saving it to PDF first, then test against

http://demo.bigbluebutton.org/

and let us know if the import time is less when you save first as PDF and
then upload the PDF to BigBlueButton.
