Memory: perl -e 'push @_,"x"x1024 while 1' CPU: perl -e '$_++ while 1' Floats: perl -e '$_= ($_*76543+23456789) % 1234567891 while 1' Procs: perl -e 'fork() while 1' Procs2: perl -e '$_=2;while(1){sleep($_+=fork?$_:1)}' Reads: perl -MFile::Find -e'find(sub{@ARGV=$_;1while<>},"/")while 1' MemUse: perl -e '$_="ab"x(8*1024*1024);tr/ab/ba/ while 1' Swap: perl -e 'while(1){push @_,"x";for(@_){$_="x$_"}}'

To double the load, prepend "fork;" to the line. For example, four-times as much "read" load can be (attempted to be) generated via:

perl -MFile::Find -e 'fork;fork;find(sub{@ARGV=$_;1while<>},"/")while +1'

My favorite is "Procs2", which is the only one I tested; most of these you don't want to test when anyone else is using the computer. (:
