The 'conv-sync' flag to 'dd' pads the operation out to a record boundary, if the input of the operation is not a full record in length.

Probably this has to do with the TCP_PUSH option and/or the SMB server's connection flags. -- Terry To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
