------- Additional comments from [email protected] Mon Mar 9 09:23:17 +0000 2009 ------- @kohei, as you can see from the data I have tested the CWS koheiformula02 and the master it is based on. The difference is there. 'Simply modifiying the data retrieval' from Calc is what must have caused this performance degradation. While loading the attached document break into the very end of method AreaChart::createShapes(). Watch variabels nSkippedPoints and nCreatedPoints on the fourth hit of the breakpoint. There is a performance optimization that skips points in case they are equal (on given resolution) to their predecessor. Before koheiformula02 about 2000 points were skipped and for some 5500 shapes were created. With koheiformula02 no point is skipped anymore. Creating shapes for all data points then takes much more time in the drawing engine (which is a separate problem and issue of its own). But the question here is why the data is so different? --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
