A performance change should improve the measured workload without sacrificing correctness or wasting capacity. Which measurements and bottlenecks should be considered first?

Measure application runtime separately from compiler performance. For slow typechecking, inspect project size, declaration dependencies and unusually complex generic types. Incremental builds and project references can help suitable repositories, while runtime speed depends on the emitted JavaScript and its execution.
