Prevent unnecessary FS calls about duplicate-package-checker-webpack-plugin HOT 4 OPEN

Thanks for opening this issue @gaearon, this definitely seems like it could cause performance issues in big projects. I'll look into it.

Note that after some discussion, we might not include the plugin after all. I'm worried it will too often be unactionable especially for tiny deps where this doesn't matter (e.g. is-path-regex or whatever). But I figured it's still worth raising an issue here.

That's a good point in the context of CRA, I think it all depends on the type/magnitude of the project and what the developers deem important in the context of that project. Maybe we can make the plugin configurable to make it more appropriate for use with CRA, such as setting a minimum size for deps before warning?

That would make sense, but it's not obvious how the plugin could measure that.
