I tried to load the CSV that I most recently imported into Google Sheets into this hosted Grist and it choked. The behavior of the progress bar implies some kind of super-linear algorithm.

The most important component of "alternative to Google Sheets" is function. "Open core" is an aesthetic matter of little interest to most users.

It's a Node app, so CPU-bound work will run linearly on a single thread unless work was done to break up work into multiple processes or worker threads.

It’s behavior was more suggestive of Zeno's paradox than of single-threadedness.

This was my experience with a well. I was testing with a 36MB dataset and it was choking. The CPU was sitting at 4% usage.
