`{ restructuring: true }` performs worse in both speed and size (after compression) benchmarks #432

Open tbjgolden opened 3 years ago

tbjgolden commented 3 years ago

Ran some benchmarks against different minifiers and discovered that the restructuring can actually perform worse after compression, and even if it sometimes is better - it runs much slower.

Two main points:

Perhaps it might be worth considering changing the default to false?
Perhaps the focus should be redirected towards actual compression speed vs compression ratio as there is more room for improvement there

some added context: general purpose compression is used on 85% of websites according to: https://w3techs.com/technologies/details/ce-compression
