--- Comment #3 from Petr.Udalau <[email protected]> 2009-11-23 02:54:25 UTC --- As I understood main idea is to use common classes(Cell, Sheet, Workbook) for HSSF and XSSF and use Mappers(or Writers) to save workbook into needed format. It will be suitable because parsing and saving HSSFWorkbook and XSSFWorkbook takes different memory and process resources. In addition it will good for evaluation. I created simle test with sheet that contains big number of formulas and run it with profiler. Test contains parsing of workbook and evaluaion of all formulas two times. Results: Step HSSF XSSF Parsing: 10735ms 19859ms The First Evaluation: 5046ms 18234ms The Second Evaluation: 485ms 922ms Methods of formula parsing(during the First Evaluation) and getting type of cell(during the Second Evaluation) takes most of time. -- Configure bugmail: https://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
