Busy Time : Transactions Vs. Observation Period
7. Server Utilization: The percentage of server capacity used during the
Observation Time.
Utilization (%) = (Busy Time /Observation Time) * 100.
For Example: For an Observation Time of 50 minutes if the server is busy for 40
minutes, the Server Utilization(%) = (40 / 50) * 100 = 80%.
8. Rendering Throughput: The average number of rendering transactions
completed during Busy Time.
Rendering Throughput = total rendering transactions completed / Busy Time.
For example, if 150 rendering transactions are completed in a busy time of 50
minutes, then the throughput would be 150/50 = 3 transactions / min.
9. Arrival Rate: The number of arrivals per unit of time.
Arrival Rate = Total transactions arrived / Observation Time
For example for a total of 1500 rendering requests arrived, during 50 minutes
Observation Time, the Arrival Rate = 1500/50 = 30 transactions / minute.
10. Response Time for a rendering transaction: It is the total time taken to
complete a transaction from its submission to completion.
Response Time= Queue Time + Processing Time
For example if a server running with 2 the rendering transaction Tr1 goes to
renderer1, Tr2 goes to renderer2, Tr3 waits in queue until one of the renderer
becomes free. The response time for each rendering transaction is as shown below.
