in reply to How to generate 'fake' memory load?

See also: one-liner hogs. There are at least two flavors of "memory load". Allocating a large string mostly just ends up consuming swap space. Continually updating the contents of a large string can consume physical memory (if the process doesn't just lose out in the fight to keep access to that limited resource).

    Reading can do the same thing as updating. For instance try the following to allocate about 10 MB of memory and actually keep it active: 
    perl -e '$_ = "x" x 10_000_000; $_ .= "y"; sleep 1 while /y/;'

    Update: kyle caught a typo where I switched variable names. Fixed.
