Have you ever encountered a situation in the browser where 32k ops per second from underscorejs wasn't enough?

How many rows/columns were in the table being repopulated? 10 times in 2400ms doesn't seem that bad - it's 240ms per refresh. Is this too slow for your use case?

The 250ms gain on rendering 1500 rows - is this something you think needs to be optimized? I can't imagine a scenario where all of those rows would fit on the screen at once.

I ask as the main area of focus for the framework seems to be speed, and I'm curious to know what inspired you to make it.
