docgen running slow

[webratz]

version "6.3.23"

running jsii-docgen on my CDK libary project takes about 1.04 minutes The project itself isn't very big, it has some external dependencies though.
I'm wondering if that is expected, and if not, what would be a good way to figure out why it takes so long.

I have created a flame graph, and it seems to spend lot of time in copy.js and glob.js which hints to FS operations. (I can share the underlying data, its just too big to upload here)

[agdimech]

I believe it copies the entire tree (including node_modules) instead of operating in place. This would explain why it takes so long as it is busy copying files.

[webratz]

is this intended behaviour, or just something that happens accidentally?

[agdimech]

It was intentional however this PR will remove that logic and will significantly improve performance.

#644
