Chapter 10: Dealing with Performance issues Flashcards
A ________ is when a component limits overall performance.
Bottleneck
______is the overall effectiveness of how data moves through the system.
Performance
______ combines your computer’s RAM with temporary space on your hard disk
to increase the amount of available memory.
Virtual Memory
Windows ________ is a powerful tool for understanding how your system resources
are used by processes and services.
Windows Resource Monitor
______ is the process of balancing battery life with performance.
Power Management
A _______is a collection of hardware and system settings that manage how your computer uses power.
Power plan
The default paging file size is_______ times the total RAM.
equal to 1.5 times the total RAM.
A _______is when a program grabs some memory for some reason and is not able to release the memory when it is done with it.
Memory Leak
A _______is done by analyzing the performance when the system is running normally and within design specifications.
Baseline
______ is the amount of committed virtual memory for a process that can be written to another storage medium, such as the hard disk.
Page Poo
Which of the following is NOT typically a bottleneck in a computer running Windows 7?
Audio
Virtual memory in Windows 7 is known as a ?
Page Filing
What program gives you a quick glance at a system’s performance and provides information about programs and processes running on your computer?
Task Manager
To terminate a process, you would use ?
Task Manager
What MMC snap-in provides tools in analyzing system performance?
Performance Monitor
The processor utilization should NOT be consistently above ?
80%
The average disk queue length should NOT be more than .
2
Which power plan does NOT come with Windows 7?
Performance Saver
What should be the maximum pages/sec?
20
What can make your disk appear slow over time?
Disk defragmentation
True or False
Sometimes by relieving one bottleneck, you may trigger another bottleneck.
True
True or False
If the paging file usage is larger than 1.5 times, you should increase the memory.
True
True or False
A page fault occurs when a process attempts to access a virtual memory page that is
not available in its working set of RAM.
True
What is a Resource Monitor?
allows you to view information about the use of hardware (CPU, memory, disk, and network) and software (file handles and modules) resources in real time.
What is page Fault /Sec?
A page fault occurs when a process attempts to access a virtual memory page that is not available in its working set in RAM. If the pages/sec is 20 or higher, you should increase the memory.
What is Interrupts/sec ?
The numbers of interrupts generated by hardware the processor was asked to respond to. A sustained value over 1,000 is usually an indication of a problem including poorly configured drivers, errors in drivers, excessive utilization of a device, or hardware failure.
What are the three (3) Power plans for Windows 7
- Balanced
- Power
- High Performance
What is the Balanced Power Plan?
Offers full performance when you need it and saves power during periods of inactivity. This is the best power plan for most people.
What is the Power Saver Power Plan?
Saves power by reducing system performance and screen brightness. This plan can help laptop users get the most from a single battery charge.
What is the High Performance Power Plan
Maximizes screen brightness and might increase the computer’s performance in some circumstances. This plan uses a lot more energy and will reduce the amount of time that a laptop battery lasts between charges.
