Expected Behavior

Unless I'm missing something, read_mode_threshold enables synchronously sending files smaller than the set threshold:

https://github.com/actix/actix-web/blob/main/actix-files/src/chunked.rs#L80-L84

Current Behavior

However, the docs for actix_files::Files::read_mode_threshold and actix_files::NamedFile::read_mode_threshold state:

When a file is smaller than the threshold (bytes), the reader will switch from synchronous (blocking) file-reads to async reads to avoid blocking the main-thread when processing large files.

Possible Solution

It looks like the corresponding statements in the docs need to be inverted.

Steps to Reproduce (for bugs)

N/A.

Context

Noticed this while cargo vet-ing actix-files 0.6.8. Then checked both 0.6.9 and the main branch.
