I have a sample grid with BIG dataset (50000 rows and 30 columns).
Loading time without lazyloading is correct.
scrolling,filtering the box is correct (for that dhtmlx grid is amazing)
in my grid i have one checkbox, it is the only updatable column.
when click a checkbox on ONE row, the delay was about 5 seconds for the checkbox to change !
it was an unacceptable delay so i check why,
after many tests the issues were :
- removing “adjust:true” decrease the delay from 5 secs to 2 secs
–> note that in the case of a checkbox, size of column stay unchanged
- removing all footer decrease the delay from 2 to 0.5 secs
–> note that in my case checking or unchecking box have no impact on the footer row
I try to make a sample with your large dataset but… it is not enough large to have impact (only 10000 rows and 4 column) so no delay issue.
note that :
- i remove the adjust true option
- i keep the footer
so presently i have a 2 secs delay when checking/unchecking box…it’s not crazy but acceptable
hope this test may help others.
