Working on Calc Performance Bottlenecks
Eike Rathke

Users sometimes rightly complain about the time it takes to load and calculate complex spreadsheet documents. Recently I worked on profiling documents to identify performance bottlenecks. The first outcome is summarized on the specific bottlenecks wiki page. You will like to hear that the Zaske case how I call it, where Excel needed 1.2s and Calc 24s to update results, is solved and Calc now, in a CWS, is on a level with Excel.

The next weeks, except for getting some CWSs ready for QA and pending work done for the ODF formula subcommittee, I'll mainly focus on changing implementation and do further profiling. I'm quite sure there are several opportunities for improvement left..

From 24s down to 1.2s is very impressive. Certainly something we as user will recognize.
As a matter of fact it's important for me to get work done as fast as possible. Waiting for such operations is painfull. If a colleague is telling you that EXCEL did the job way much faster one starts to reconsider EXCEL is an alternative to OOo.
Anyways, well done. Excellent work. Thanks

Hi, please don´t forget Calc´s performance issues in connection with DataPilot!
http://de.openoffice.org/issues/show_bug.cgi?id=85161
We have ten minutes in Calc, where Excel needs a couple of seconds!
Cheers, Stefan.
