title: what is scheduler latency?
body: <p>This seems to be a basic question, but i couldn't find answer anywhere in googling it.</p>
  
  <p>As Far As I Understand, scheduler latency is the time incurred in making the task runnable again. I mean, if there are 100 processes namely 1, 2, e.t.c, then they are executed let's say in order starting from 1. So the latency is the time that the process 1 is executed again. which means that the latency is the waiting time of the process as well as the waiting time of it when it is in runqueue ready to execute. </p>
  
  <p>Or </p>
  
  <p>i misunderstood whole point and sheduler latency is just nothing but the context switching time between the processes?</p>
