It's a good point that a lot of editor latency issues aren't specific to typing. One thing that has always annoyed me is if an editor has slow find-and-replace for large files or projects.

I also find it interesting that you claim that humans don't notice latency under 100ms as though it is established fact, considering the OP spends basically the whole first section trying to debunk that incorrect but commonly quoted belief.
