$0 [ -b path ] [ -s server ] [ -p port ] [ -m mntpoint ] [ -l path | seconds ]
Generate load, using an assorted set of commands and optionally:
- hackbench if the path to the hackbench binary is specified with -b;
- nc to send TCP data to "server" port "port" if -s is specified (if -p
is not specified, the port 9, aka discard is used);
- dd to write data under "mntpoint" if -m is specified.
during the runtime of the LTP test if the path to the LTP installation
directory is specifed with -l or during "seconds" seconds.
