Do you know of any assessment of performance characteristics for said ‘piece tables’? The thrust of TFA is essentially a performance comparison, so I can’t help but wonder why this implementation wasn’t addressed if it is present in one of the most widely used code editors. Also, VS Code is not known for its responsiveness for text editing, is this due to the ‘piece table’, or more likely, due to architectural decisions in the application more generally?

I’m not really up-to-date on any text editing implementation details, so if this is basic/common knowledge feel free to just tell me to Google it.
