Depends on the data, I guess, if they are all visible at once 
then you basically have to very carefully write your own GPU 
render stage for that view and carefully cache things that does 
not move by rendering them to buffers (in GPU memory).

They have some inefficiencies in how the DOM is being manipulated 
(like setting numeric styles as strings, but there is a fix 
coming for this, maybe it is available already?)

But if you deal with large number of items you basically can 
write your own view and dynamically create elements as the user 
scrolls. You do need to estimate the height though.

You can have a web-worker handling the dataset and basically 
stream it to the main thread that does the GUI. There is a delay 
though, so it takes some tweaking.
