   -file-size <size>            the size of the local file to write to and read from (in MB, default to 256)
   -chunk-count <count>         the number of chunks to upload and download (default to 64)
   -chunk-size <size>           the size of chunks to upload and download (in MB, default to 4)
   -upload-threads <n>          the number of upload threads (default to 1)
   -download-threads <n>        the number of download threads (default to 1)
   -storage <storage name>      run the download/upload test agaist the specified storage

I’m wondering why does the -file-size command only change the size of the local file benchmark, but the upload/download to the remote storage is still 256M?

I was attempting to benchmark b2 with the free account with the 1GB cap, and would only be able to test 3 full 256M runs and wanted a 4th run of 150M with -file-size option, but it still uploaded/downloaded 256M.

The local test split 150M into 34 chunks while the remote test split 256M into 64 chunks.

Also wondering whether this has been fixed yet?

The size of download/upload is controlled by the -chunk-count and -chunk-size options: download/upload-size = chunk-count * chunk-size
