+#### --azureblob-copy-cutoff
+
+Cutoff for switching to multipart copy.
+
+Any files larger than this that need to be server-side copied will be
+copied in chunks of chunk_size using the put block list API.
+
+Files smaller than this limit will be copied with the Copy Blob API.

+
+#### --azureblob-copy-concurrency
+
+Concurrency for multipart copy.
+
+This is the number of chunks of the same file that are copied
+concurrently.
+
+These chunks are not buffered in memory and Microsoft recommends
+setting this value to greater than 1000 in the azcopy documentation.
+
+https://learn.microsoft.com/en-us/azure/storage/common/storage-use-azcopy-optimize#increase-concurrency
+
+In tests, copy speed increases almost linearly with copy
+concurrency.

+
+#### --azureblob-use-copy-blob
+
+Whether to use the Copy Blob API when copying to the same storage account.
+
+If true (the default) then rclone will use the Copy Blob API for
+copies to the same storage account even when the size is above the
+copy_cutoff.
+
+Rclone assumes that the same storage account means the same config
+and does not check for the same storage account in different configs.
+
+There should be no need to change this value.
