#### What is the problem you are having with rclone?

I have a bucket with 3 M objects and some are30m files. When i do rclone size command, it takes ages to return the output and so mc du command as well. I was wondering if there is any faster way to check the size of the bucket. I tried to put transfers and checkers to see if i can trick but it seems not worthy. Please suggest.

@asdffdsa Done, please check

Depending on the layout of the bucket (if it isn't 3m files in one directory) increasing --checkers may help.

--fast-list is unlikely to help.

Unfortunately in the S3 protocol there is no faster way to find the size of a bucket than by listing all the files.

for minio, that should be provider = Minio

it is not in one directory.. Basically commvault data. Should i try rclone size --checkers 128 remote:bucket
