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.

Hi, 
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.
