## DESCRIPTION

This command measures file copy performance from source directory to destination directory. One of source and destination url must be gfarm url (that begins with gfarm:///). Other must be file url (that begins with file:///).

Test file is automatically created but source file is not removed. When this command is executed on same parameters, source file is reused again.

  File size to be created. The default is 1M. (1M=2^20)

`-b, --bufsize` buffer size

  Copy buffer size. The default is 4K. (1K=2^10)

`-g, --gfsd` gfsd name

  Target gfsd name. Test file is created or copied on this gfsd. If no gfsd is specified, gfmd determines automatically.
