I’m trying to create an app for alarms with two tables. I need to update them with new alarms every two seconds. Tables may contain up to half a million elements, but I do not refill the table every time just add the most recent ones. But when I do that it takes time to show up and meanwhile, the page performance is very slow. Because of that when I leave the app overnight it’s either freezes or makes the app impossible to work with until I refresh it.
Here’s an example that you can try:
To start the timer you should click on any cell inside a table. After that, try to resize a window with a table or scroll and you will see that it takes time to respond and for a table to update.
Can you suggest something, please?
