Description arielt 2004-05-13 08:07:05 UTC
When playing a presentation, there are slides which load just fine, but 
after the slide is displayed correctly (which takes a very short time), the
presentation is stuck for several seconds.  During this time there is a sand
clock mark on the bottom left corner of the screen.  I don't know the reason
for this, as this occurs for both text-only slides as well as slides with
large images.  My disk does not work during that time (LED inactive), so I
believe it is not a disk read time.

    This phenomenon prevents rapid skipping of slides.  It actually limits the
speed of changing slides.  For example, if I press the PgDn button twice, the
second press would have no effect:  the first would change the slide, but the
second would fall in the period of time of the sand clock.  Only after about
5 seconds I can press PgDn again.

    This problem does not occur in edit mode, where I walk through slides very
fast.  It exists in earlier versions of OpenOffice as well.

Reassigned to Christian.

The hour glass is visible when the next slide will be prepared to show.
The time the preparation needs (the hour glass is visible) depends on the
content of the slide.

    In this case, a very significant performance improvement is necessary in
that part of the code.  It is unreasonably slow.

    I work on a Pentium III 850MHz, 256M RAM laptop, but I cannot page up and 
down between pages smoothly.  When in front of a class, this waiting time is
highly bothering.  I want to go back a slide, but I have to wait for the
*next* slide to render.  Preparing next slide is not interruptible, so moving
to previous slide is waiting in vain.

    In addition, I exported the presentation to PDF, and tested the transition.
Transition between PDF pages is by far faster and smoother than by the
OpenOffice.org (680m36 and 1.1.1) presentation of the same slides.

    Therefore, if one has no special effects in the presentation, one's best
way to present it is by PDF export.  I believe this is not the intention of
OpenOffice.org presenter.

    At first, I thought maybe I should now change this issue to ``Enhancement'',
but I refrain from that, due to its high severity.  I believe people may even
avoid using OpenOffice.org because of so poor performance.

    As far as I remember, M$ PowerPoint has much better performance (I haven't
been working with it for over a year or two I believe, but I can't remember
such slow transitions).

I reopen the issue

Please have a look if the preparation of the slide become faster in the new
presentation engine.

Thorsten, please raise this issue to OOo 2.0 and set it to fixed when you
finished with the performance tweaks for the new presentation engine
