The system utility top provides a continuous, real-time look at the system's consumption of memory and CPU resources. It lists the most consumptive process first, so finding that process that is gobbling machine resources is relatively easy. top also displays: the total operations time for the system since the last reboot; load averages; process counts for various states; the percentage of CPU time broken down between user, system, nice, and idle; memory and swap space usage; as well as the list of the processes using the largest amount of the machine resources.
