[call for review] One fix about performance improvement(xls loading)
hi, all
I have one fix need for review. Please check the below for details, thanks!
One is about xls saving:
https://issues.apache.org/ooo/show_bug.cgi?id=120586
Root cause:
in spreadsheet filter process, 'updaterowheights' will be performed for all
the objects in the document.
Resolution:
In filter process, record which sheet will contain sdrobject, then only do
'updaterowheights' for :
1.visible sheet. 2.sheet containing sdrobject. This is only for optimizing
excel8 type.
following is test result for sample file xls sample.xls(manual test), about
20% improvement.
