It's still true. You might be able to get decent performance on a Macbook 3000 (doubtful even) but anything less than that, nope. That's why many grid components use canvas rendering. It would have been a lot easier for all these grid devs to work with DOM nodes if they could.

Out of curiosity: What browsers did you test? Firefox performs magnitudes better in css benchmarks than Chrome, and I thought it is also better in handling large DOMs in general.

DataGridXL is used by 10 million end users. It's tested on all kinds of devices and browser combinations.

Browsers can handle AND update really large DOMs, but they still choke on doing all of these actions (repaint, reflow) WHILE SCROLLING, which is a different game.

Many grid components were developed many years before modern compositors and the `contain` property.
