GNU tar explicitly checks if the archive is beign written to /dev/null, and if so, it does not do any real archiving. That is, it does not actually open and read any files. This behavior is documented in http://www.gnu.org/software/tar/manual/html_section/file.html#SEC99 > I want to measure performance in terms of time required to perform tar > on a given hiearchy. so I am not sure which command is correct. In that case, create a real archive on the file system and delete it after measuring is done.
