Nick Craig-Wood	2db0e23584	backends: change OpenChunkWriter interface to allow backend concurrency override ... Before this change the concurrency used for an upload was rather inconsistent. - if size below `--backend-upload-cutoff` (default 200M) do single part upload. - if size below `--multi-thread-cutoff` (default 256M) or using streaming uploads (eg `rclone rcat) do multipart upload using `--backend-upload-concurrency` to set the concurrency used by the uploader. - otherwise do multipart upload using `--multi-thread-streams` to set the concurrency. This change makes the default for the concurrency used be the `--backend-upload-concurrency`. If `--multi-thread-streams` is set and larger than the `--backend-upload-concurrency` then that will be used instead. This means that if the user sets `--backend-upload-concurrency` then it will be obeyed for all multipart/multi-thread transfers and the user can override them all with `--multi-thread-streams`.

Nick Craig-Wood	967fc6d7f4	lib/multipart: fix accounting for multipart transfers ... This change makes sure the accouting is done when bytes are taken out of the buffer rather than put in. See: https://forum.rclone.org/t/improve-transfer-stats-calculation-for-multipart-uploads/41172	2023-08-27 23:10:58 +01:00
Nick Craig-Wood	4c76fac594	s3: factor generic multipart upload into lib/multipart #7056 ... This makes the memory controls of the s3 backend inoperative and replaced with the global ones. --s3-memory-pool-flush-time --s3-memory-pool-use-mmap By using the buffered reader this fixes excessive memory use when uploading large files as it will share memory pages between all readers.
