Please, check this example: https://snippet.webix.com/a9yy0831
As you can see, it takes a lot of time to load. Which surprises me, because the dataset has only 10k records. For example, this demo from your docs uses dataset with 148702 records, and still works pretty fast.
I also tried to use your web worker, but with no success. I end up having "Data cannot be cloned, out of memory" error message. (you can uncomment webworker-related line and see for yourself).
Is there any way to avoid this problem? To improve performance somehow? Maybe there is a way to display only N data records initially, and add all the rest data records on some user interaction?
