Could you clarify on the difference between User and Sys time?
Could you clarify on the difference between User and Sys time?
On a UNIX system, a process (an instance of a program running) will be executing in one of two modes; user mode, or kernel mode. The process will generally be in user mode until, for example, a system call is made. Then the mode switches to kernel mode in order to service the request. I believe that user time and system time corresponds to the time spent in both user mode and kernel mode respectively.Originally Posted by Kleid-0
If you are using a *nix machine (and I have assumed that you are) then look at the man pages for time and times(2)
