More specifically than what Jeff said:

        # Kernel build
        make -j 8 MAKE="make -j 8"

        # Thrash the VM system, using lmdd (part of lmbench)
        # This allocates a 256m buffer, bzeros it, then writes a pattern in
        # it 10 times. If you have 512M of memory, use 512M.
        lmdd opat=1 bs=256m count=10

        # Thrash the network
        lmbench/bin/i686-linux/bw_tcp -s
        lmbench/bin/i686-linux/lat_tcp -s
        # This won't work but you get the idea; I use xfanout for this.
        for i in a b c d e f
        do rsh $i lmbench/bin/i686-linux/lat_tcp -s `hostname` &
                rsh $i lmbench/bin/i686-linux/bw_tcp -s `hostname` &
        done; wait

There's more, but a system which can do all of that well is not one which
sucks :-)
