What exactly are the "In/Out" numbers? that's just the output from /usr/bin/time -f '%e\t%U\t%S\t%M\t%I/%O' The manual describes them as "number of file system inputs/outputs". From looking at the source, they correspond to ru_inblock and ru_oublock fields from the getrusage call. AFAIU, that means the number of non-cached read/writes. d
