time dd if=/dev/zero of=/tmp/tmps bs=512 count=2
this will show the time taken to create a 1024 bytes file at /tmp/tmps
filled with zeros
in chunks of 512 bytes, to know different chunk size and performance
differences, change the
bs value and try.
time dd if=/tmp/tmps of=/dev/null bs=512 count=2
this will show the time taken to read the file /tmp/tmps (if it exists) and
redirect it to
/dev/null (nowhere).
