How does multipart uploading affect Cloudflare R2 upload speed?

Multipart uploading splits a large file into smaller parts that are uploaded concurrently. This significantly improves upload speed by leveraging parallel processing and reducing the impact of network interruptions. If one part fails, only that part needs to be re-uploaded, rather than the entire file. Cloudflare R2, like other object storage services, benefits greatly from this approach for large files.
