I18n Performance Benchmark
What is this metric?
The total gzip-compressed size of the internationalisation library bundle. It only includes the provider and content retrieval logic after tree-shaking and minification.
Why is it important?
A smaller library size reduces the initial JavaScript payload, leading to faster download and execution times on the client.
