Interrupts are events delivered to CPUs, usually by external devices and can cause performance and observability problems for applications. Tim Cook's post explains the use of DTrace in identifying the source of interrupts and solving the performance problems caused when an interrupt "steals" a CPU from an application thread, halting its process while the interrupt is serviced. Cook calls this pinning (the interrupt will pin an application thread if the interrupt was delivered to a CPU on which an application was executing at the time). Cook cites several DTrace scripts to use in assessing the effects of pinning.
