Windows Vista's performance
How to use Vista’s built-in tools to find and fix the problems that
stand between you and an excellent Vista experience
All of the following statements should be
true:
- On a new PC built with up-to-date hardware, Windows Vista should start
up in a minute or less and shut down in 30 seconds or less.
- Video performance and audio playback should be smooth and
glitch-free.
- Programs should open quickly and do their work without affecting your
ability to perform other tasks.
- File transfer speeds should be limited only by the capabilities of your
hardware (disk, controller, and network).
- System crashes should be nonexistent, and application crashes should
hang the faulting program only, without affecting other programs.
If any of those conditions fail, you have a PC that needs
fixing.
The formula for getting excellent performance out of a Windows Vista PC is
straighforward:
- start with quality components
- make sure every piece of hardware has the right drivers
- make sure every piece of software is up to date
- fix any performance bottlenecks.
In this How-to guide we will introduce you to Vista's four built-in
tools you can use to track down and fix performance problems.
Let Windows identify performance issues
- Press Windows logo key + E to open Windows Explorer, and then click
System Properties on the Command Bar.
- In the System dialog box, click the Windows Experience Index link in
the center of the dialog box.
- then click the Advanced tools link in the Tasks pane on the left side
of the dialog box.
- Windows Vista monitors performance constantly. If you’ve been
experiencing performance problems, they’re going to be called out at
the top of this dialog box.
- Click any of the links in this section to open a dialog box with
precise, detailed information about the driver or program causing the
problem. Armed with that information, you can look for an updated driver or
a change in settings that can restore performance to excellent levels.
Gather hidden system details
The Windows Experience Index rating is marginally useful. If your graphic
adapter has earned a low score like 1.0, for example, you know that the
system is using the built-in SVGA driver and you need to go find a driver
written for your system’s graphics hardware.
The detailed system information is far more interesting and useful. To
display the full listing, go back to the Performance Information and Tools
page and click the View and print details link just below the index
numbers:
Clicking that link leads to a page that shows details about the major
subsystems in your PC:
- Processor shows the make and clock speed of your CPU
- System displays the manufacturer and model of your PC, the
amount of installed RAM, how many processor cores are present, and whether
the system is capable of running a 64-bit operating system
- Storage lists all available hard disks and media drivers, along
with the amount of free space available on each one
- Graphics provides details about your graphics adapter, how the
GPU and system memory are being used, the current system resolution, and
which display driver is currently in use
- Network lists the name and model number of all available wired
and wireless network adapters
Armed with this information, you can search the PC manufacturer’s
website for the latest BIOS; BIOS updates released in the past year or so can
have a huge impact on performance and reliability. You can also track down
up-to-date drivers for graphics adapters and network cards, both of which are
likely to have a significant positive effect on performance.
Get the most out of Task Manager
Task Manager is useful for getting a quick snapshot of performance and
system activity. Here’s how you can put it to best use.
Learn how to open it up: The direct shortcut is: Ctrl+Alt+Esc.
You’ll also want to click the Show processes from all users
button in the bottom left corner to see system-owned processes as well:
Make the following tweaks to Task Manager:
- On the Processes tab, click the CPU heading, which sorts the display of
running processes so you can see those that are putting most demand on your
processor.
- Customize the display of columns to show the Process Identifier (PID)
of each one. That can come in handy when using other tools.
- Sort the Services tab by PID to see which services are grouped under a
single instance of Svchost.exe. If that service group is hogging CPU
resources, you can narrow down the list of potential offenders here.
- Finally, click the Performance tab to see rough graphs that show CPU
and memory usage.
For anything more than rough snapshots, click the Resource Monitor button
at the bottom of the Task Manager Performance tab to open the Resource
Monitor program.
Learn to use Vista’s real-time performance sleuth
The main Resource Monitor window consists of five collapsible bands. The
screen shown here has the Resource Monitor and CPU bands expanded, with the
other three bands collapsed.
Each of the four graphs in the Resource Overview section displays a
different, live aspect of system performance. [Hint: You can pause the
display any time by clicking Stop or Start from the Monitor menu.] Each graph
tracks the most recent 55 seconds of its assigned metric, and each graph has
a blue and a green line. For the CPU graph, the blue line indicates the
amount of the CPU allowed by current power management settings, while the
green line tracks the total load of all running processes. This system is
using the Balanced power scheme, which means the CPU is throttled down for
normal use but makes more processing power available when applications demand
it.
If you move the mouse pointer over a graph, it turns to a crosshair. Click
once to expand the corresponding band below the Resource Overview. Click
again to collapse that band. The default sort order for the CPU details band
is the last column, Average CPU, which helps you spot which programs are
making persistent use of the processor.
By expanding the details band for each of the four areas that Resource
Monitor tracks, you can quickly scope out performance bottlenecks. The
heading for each band includes aggregate statistics, while the expanded area
lists details. Under the Disk heading, you can click the Read (B/min) or
Write (B/min) headings to sort the display and see processes and the exact
files with which they are working.
You can use the detailed statistics in the Memory section to see which
programs and processes are using the most RAM. You’ll find far more
detail here than in the rudimentary Task Manager display.
In our experience, most Windows Vista performance problems can be solved
by fixing one or two issues. The trick is finding those issues. With the
information presented here you’re better prepared to get past those
snags and allow Vista to achieve its full potential.
