[Octave-bug-tracker] [bug #59277] xls2oct and/or openxls behave unexpected

[Dennis]

Follow-up Comment #4, bug #59277 (project octave):

Here is another thing that is bothering me. I was wondering why there is a
huge difference between the profile results of my dummy case and the real
sheet that I use. I am referring to the second call of the test script (when
it uses OCT). The most time consuming function is cell2mat. But why the
difference between my original sheet and the dummy?

To test this, I have stripped my real Excel sheet step by step. First removed
references between sheets, removed conditional formatting, etc. That all
didn't do much. What really made a big difference was removing *other* sheets
in the workbook that contained quite a bit of text. For some reason the
presence or absence of these other sheets had a huge impact on the time used
by cell2mat. This seems strange to me, because the xls2oct function gets a
specific worksheet as input. Why would the presence or absence of other
worksheets make any difference on the time spend on cell2mat?
