<p>Lookbusy is a simple application for generating synthetic load on a Linux
system.  It can generate fixed, predictable loads on CPUs, keep chosen amounts
of memory active, and generate disk traffic in any amounts you need.
</p>

<p>Lookbusy is not a load <em>simulator</em> -- that is to say, it does not
attempt to model the specific actions of real-world applications for
benchmarking or other purposes.  Rather, lookbusy makes a system just as busy
as you'd like it to be.</p>

<p>When generating CPU load in particular, lookbusy will attempt to keep the
CPU(s) at the chosen utilization level, adjusting its own consumption up or
down to compensate for other loads on the system.  Load can be induced either
at a fixed level, or at on a repeating cycle (for example, reflecting a daily
traffic load curve.)</p>

<p>Lookbusy free software, released under terms of the GPL.</p>
