Re: [libreoffice-users] Consistently poor Impress performance in Mac OS X

Hi :)
Impress is not brilliant.  It's getting there but i think most of the work went into Writer and 
Calc.  There are alternatives that each have slightly different aims.  

However, 500-800Kb images are quite large.  If you open one of the images with Gimp (or something) 
you could resize the image down to something smaller than bill-board sized.  

Since the issue is possibly more important for websites it is easier to find a "How To" such as 
these  
http://www.gimp.org/tutorials/Lite_Quickies/

http://www.ahotw.com/2008/08/09/gimp-image-cropping-for-web/
http://www.geekazine.com/guests/basic-gimp-preparing-pictures-for-the-web

I guess "Ponderous" is an antonym of "snappy" but it doesn't quite convey the frustration quite as 
well as the way you used.  Plus it's waaay outside the vocabulary range of most native-English 
speakers.  Apparently the average is around 100-250 words (depending on which study you read).

Hello,

This is a question I asked in ask.libreoffice.org, but did not get a useful reply:

I've got the latest Impress running on my MacBook Pro with Mac OS X 10.6.8. (but this problem 
existed in previous versions, too)

For the past few months I tried really really hard to make all my
presentations with Impress. The big problem is that it's performance is the exact opposite of 
snappy. (what is a good antonym for snappy?)

After adding images (they are each just 500-800kb JPGs) to, say, 20 slides, Impress grinds almost 
to a halt. Things respond 1-2 seconds after the mouse click.

This is especially frustrating when clicking, holding, the dragging, because there is always a 1-2 
second lag between each step. For instance, if I click and drag the corner of an image to resize 
it, the motion is not smooth, but rather occurs in "jumps". Another instance would be when I click 
on a slide to select/show it in the main window. If I move the mouse cursor away after clicking on 
a slide, the lag makes Impress think I am dragging and re-ordering the slide! And of course there 
is a few seconds delay here as well.

So my question is: What's wrong that's making Impress perform so poorly?? My Mac has a Intel Core 
i7 2.66 gHz CPU, advanced Nvidia GT 330M graphics, and 8.0 GB of memory, it should be overkill for 
something like this! I tried tweaking the number of objects kept in memory, size of objects, etc. 
to no avail.

Is it just because Impress has poor performance? (in which case I think it really need to be 
improved) Or am I doing something wrong??? M$ PowerPoint and Apple Keynote works beautifully and 
snappily, but I wish I could use Impress!

Thanks!
