The grid requires an excessive amount of resources to display data

[Piotr]

I have a grid of eight columns. In the first column there is a date, in the second one there is some text and in the others there is individual text and numbers. The data is loaded in chunks (about 500 records each) using "virtual scroll". The problem is that loading data into the grid increases the RAM consumption enormously. After loading more than 2000 records, the application becomes unusable (everything works with a delay). The Chrome task manager shows almost 1,5 GB used memory but the real data size is about 0,8 MB. I gave up with a more extensive grid (details, filters) but the problem still occurs.

I am asking for help, thank you
