A single-threaded compute-intensive program elapses 100 s when running in a system with one processor. What would the new elapsed time be if we upgrade the system with a processor twice as fast?

IOPS (Input/Output Operations Per Second), is a performance measurement of
- Response Time
- Velocity
- Throughput
- Usage
The SAP Application Performance Standard, known as SAPS, is a performance measurement of
- Response Time
- Velocity
- Throughput
- Usage
The storage subsystem XYZ delivers 10000 IOPS with an IO average response time of less than 5 ms. This implies that allowing a 10 ms response time per IO, it would deliver 20000 IOPS.
- True
- False
In a typical OLTP scenario doubling the workload, in the sense of doubling the number of users, implies doubling the response time.
- True
- False
In a typical OLTP scenario doubling the workload, in the sense of twice heavier requests, implies doubling the response time.
- True
- False
Doubling the processing capacity, in the sense of doubling the number of processors, implies halving the response time.
- True
- False
Doubling the processing capacity, in the sense of upgrading to a twice faster processor, implies halving the response time.
- True
- False
In a typical OLTP scenario an usage greater than 65% necessarily means bad response time.
- True
- False
