Rainer_Temme@xxxxxxxxxxxxxxxxxxxxxx says...
dd if=/dev/urandom bs=1024 count=1024 >1m
I understood him to mean that he wants to compute the random data on the
fly as opposed to reading it from disk to avoid having the file system
and disk system limitations be the upper limit on his throughput. He
wants to choke the pipe and the disk may be slower than the disk.
HOWEVER, your suggestion still has merit as he doesn't have to write to
disk, but lay out a huge random array in memory and loop through that
instead.
