They provided Darin (and through Darin, me) a tiny benchmark which use innerHTML repeatedly to update a table, in a similar manner to how at least some versions of spreadsheet handle scrolling. Looking at this microbenchmark in a sampler shows some low hanging fruit which I've filed as separate bugs and blocked here. 678087 1 154365 eric 2012-07-25 08:32:01 -0700 Created attachment 154365 grid microbenchmark from fishd 678091 2 dglazkov 2012-07-25 08:35:47 -0700 If this is a revised version of https://github.com/dglazkov/performance-tests, Juilen has been working on some of the issues. Are you guys coordinating? :) 678094 3 eric 2012-07-25 08:37:09 -0700 This is some html file Darin sent me via email yesterday.
