Increase cache performance #19

Closed darky closed 5 years ago

darky commented 5 years ago

I investigate cache structure, seems it can be optimized for increasing performance.

In this case: https://github.com/plantain-00/type-coverage/blob/1e6c786ebe26895e2b69b9027579fd2aa18b8de5/src/core.ts#L43 uses find with time complexity O(n) But if cache will be appeared as object, where key is file path, complexity will be O(1)

Also sha256 for hash generation so heavy, sha1 better for this purpose Or maybe you can see other fastest algo: https://embed.chartblocks.com/1.0/?c=586a7b509973d2205b8d3849&referrer=https%3A%2F%2Fmedium.com%2Fmedia%2F3197da6695a99369671f5dd53af74b49%3FpostId%3D8052b6923a3b&t=ddcb12386fa2d04#

But it require to compile native deps :(
