Hi Mathias
I think that your analysis correctly describes why an XML based format
will always be slower than a optimized binary format. OOo has some
special problems here though, even with an XML format it could be much
faster. This is something that is worked on with high priority.
i totally agree
in fact this is even shown in Mr OU scientific-like analysis as there is
some numbers with Excel XML format
Excel creating native XLS baseline baseline
Calc creating native SXC 98 x slower 51 x slower
Compressed MS XML total time 15 x slower 22.5 x slower
the ratio excel Binary / OOo1 is 98/51
the ratio excel XML / OOo1 is 6.5/2.25
the second (XML based) has to be focused
the first is non-sense to me (eg: what about portability of the document
troughout systems)
This analysis is legitim. The used datas are the upper-limit i think you
cant ask to a spreadsheet
BTW, Mr OU conclusion is false, favorising its point of view. First, he
has to sell his paper. Saying that OOo is 100x slower than 6x (or 2
times in reading) is less attractive isn'it
Btw, his long term fight is to show that XML is not good and user always
run after speed ... and Ms give them.
