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.
