Details

The bundle size of Rspack and Webpack artifacts are very different.

Webpack

Webpack creates smaller chunks, the difference in size between chunks is not as great as Rspack.

And the total size is smaller, but the gzipped size is larger than Rspack.

• Total size: 6.16 MB
• Gzipped size: 1.74 MB

Rspack

Rspack creates a 3.73 MB large chunk, and the total size is larger.

• Total size: 6.78 MB
• Gzipped size: 1.71 MB

Now (Rspack v0.6.1) the total size is smaller than webpack and no more large chunks, so I will close this issue.
