Not sure but I think startup time is impeded by the fact that tsc has to parse and synthesize around 20k+ lines of TS definition files. These require a parse for hoisting, require scanning lots of comments which are only used in LSP mode and are not a optimised format to parse. On the other hand Ezno a semi compatible TypeScript compiler can use a more low level binary format which is only one pass and whose name references are already resolved https://twitter.com/kaleidawave/status/1596445852918325250?s... . This is only really possible because it is written in Rust so low level byte and memory management is relatively simple |
