Are you talking about user space process or in kernel space process/thread? And what do you mean by input and first response by process ? And also what do you mean by first context switch/interrupt or so ? By the way you can consult this doc in which a example code is given for measuring a response time of doing some operation or system call http://www.linux.it/~rubini/docs/ksys/ksys.html -- Fawad Lateef -- Fawad Lateef -- Kernelnewbies: Help each other learn about the Linux kernel.
