I understand that XML is a rather verbose format, but even in binary you have to
implement some kind of "serialization" of the data-structures you use to
describe the document in memory.

However, the problem I'm having is not just a mather of Calc being a fixed
factor (say 2 or 4) slower than Excel to do the same thing.  The factor is not
fixed as you can gather from the table of values I posted initially.

It doesn't seem to be a problem with a specific version or platform since I
tried it on different machines, OSs and OOo versions.

But your results don't measure up with mine.  Your tests with a 10K lines file
got aproximately the same time to open it and to save it.  But my results were
very differente.  On OOo 1.1.2 it took 14 times more time to save the 10K lines
file than to open it, and on OOo 1.9.90 it took 7 times more time.  (I just did
the test again and got the same results as before.)

I'm wondering if you performed the same test.  Note that I open the CSV file and
save it as a SXC.  The saving is what is taking so much time.  I just did it
again (with OOo 1.9.90) but this time I saved the file as a CSV with another
name and it took half the time it has taken to open.  So, please confirm again
that you tested exactly the same thing as I did, saving the spreadsheet as a SXC
and not as a CSV.

And thanks for your patience. :-)
