Performance
oReducing Response Time (Execution Time)- the time between the start and the completion of a task. Total time required for the computer to complete a task, including disk accesses, memory accesses, I/O activities, operating systems overhead, CPU execution time, etc.
o
oIncreasing Throughput-the total amount of work done in a given time.
oPerformance and Execution time relation for a computer X can be given as
PerformanceX = 1
--------------
Execution time X
oIf comuter X is n times faster than computer Y then the execution time on Y is n times longer than it is on X :
o
PerformanceX = Execution Time Y = n
---------------- --------------------
PerformanceY Execution Time X
oElapsed Time - total time to complete a task, including disk accesses, memory accesses, I/O activities, operating systems overhead, etc.
oCPU Time – the time the CPU spends computing for the task and does not include time spent waiting for I/O or running other programs ( response time = elapsed time not the CPU time )
oUser CPU Time – the CPU time spent in the program
oSystem CPU Time – the CPU time spent in the operating system performing tasks on behalf of the program
