Performance issues observed with grid after migration to Pega7
Performance issues are observed in the presence of multiple grids on the UI after migration to Pega7 compared to Pega 6.2 sp2 version. Overall performance is relatively poor in IE browser compared to Chrome and Firefox.
No error messages, relatively high amount of time for screen load and data fetch.
Steps to Reproduce
Load a UI portal screen containing multiple girds with large data sets.
Tyring to load large datasets at once into the grids was slowing down the UI performance.
After migration to Pega 7, by default grids had pagination format as"None". Modifying that to "Progressive" improved performance significantly.
