Libre Office getting slower

[cyblance]

I got a .pps file (5.4MB) sent to me including images of the top 7 woman from Brazil. The show which I can only guess would take about 4 minutes in Windows took over 10 minutes to view. Whilst - due to the subject matter - I am not complaining, there definitely seems to be a growing concern that any file over 2megs seems to battle on LibreOffice as well as OOo. I have been using these for over a year now so this is a new issue.

My question is - are Microsoft making the files harder for us to read? Certain xlsx files don't open at all if they are over 2MB large.

The computers I have tried to open these on are:
Acer Travelmate 7320, 1.73 GHz - Ubuntu 10.4 Open Office 3.2
PC - Intel Quad Core - Ubuntu 12.4 Libre Office 3.
I also increased my memory requirement in options (didn't help)

I Had to fire up an old windows machine recently to view these excel documents. There must be another solution?

I don't know about OpenOffice but LibreOffice does struggle with large files even if they're native (created in LibreOffice). So, for once, I wouldn't blame MS.

Strangest thing though - is that some files - (in this case 4MB) open properly. They contain confidential information so I can't post up the examples.

I will check to see what's different about the 2 files and post results later.

Not sure if this is worth anything but here is the output from XLSX files when viewed in the archivemanager. Note that the 3.8 MB file is opening and some smaller files aren't

Update

I'm marking this as solved - (which I don't know how to do formally) - as I am now able to open these files. (time heals all)

Thanks and well done to all involved. :p
