Would you say it's fair to compare the memory usage / loading time of a huge TS file in VSCode vs in vanilla Vim, when one loads Language Services and provide advanced language features while the other just does Syntax Highlighting?
Or comparing Vim against Sublime for loading large files, when Sublime needs to draw the very fine and useful minimap but Vim doesn't?
In addition, most of these perf tests are extreme cases, whereas some editors are optimizing for more common use cases.
