The application linked here is only showing 270 cells at once. I think even the slowest framework can handle that...
It's when you get to thousands/tens of thousands of data points that things can really slow down without good optimizations, especially if you're modifying the DOM or manipulating SVGs (as opposed to drawing to Canvas, typically).
Yes...? I think maybe there are some threads getting mixed up here? There are some sibling/cousin threads discussing performance more in depth. My post you replied to is just pointing out that 300 cells isn't really enough to measure any sort of meaningful performance.
