# Generate 10000 small files with file size less than 1 MB.
# 1) Little files are generated from /dev/zero instead of /dev/urandom
# 2) skip switch is required b/c it allows each file to have different sizes
# 3) one can change value in variable: `numFiles` to suit your
# needs
#
# One can utilize this script to do performance testing on linux systems
# more codes may need to be added to print out various information
