cpulimit is a simple program that attempts to limit the cpu usage of a process (expressed in percentage, not in cpu time). This is useful to control batch jobs, when you don't want them to eat too much cpu. It does not act on the nice value or other scheduling priority stuff, but on the real cpu usage. Also, it is able to adapt itself to the overall system load, dynamically and quickly.

Maybe that Linux system sluggishness is being caused by the CPU? It's worth a look :)

Atmel has launched an interesting new chip line aimed at reducing NRE (non-recurring engineering) expenses associated with ASIC (application-specific integrated circuit) development.
