steps to reproduce
- load the attached Excel file
- scroll down (or right) 15 rows for each time
- scroll several times and observe the row rendering behavior
result
There is an obvious blank content appearing after a scroll for 3 seconds.
expect result
Showing the blank content as short as possible
workaround
- preloadRowSize="2000"
debug info
- setAutoFilter() takes too much times during scrolling. see rendering-filter.cpuprofile
- ignoreAutoHeight="true" doesn't help on this case
steps to reproduce - long scrolling
- load the attached Excel file
- scroll down for over 100 row for each time
result
The time to show the blank content becomes even longer. ZSS takes more time on js setAutoFilter(). Please see longScrolling.cpuprofile
