Everyone wants a fast Windows 7 computer. This is especially true
of people who play games. So the question is what makes a Windows 7 computer
fast? How can you speed up your Windows 7 computer without paying an arm and a
leg to increase the speed.
Several things make a computer fast. The most important is keeping
it clean. A new Windows 7 computer is like my 2 car garage in 1985. At that
time it help 2 cars no problem. Today is holds no cars. There is no room
because other stuff has been stored there.
The same is true of most computers today. When they were purchased
they were fast because they were empty of software. Over time software
accumulated in the computer. The most egregious software is memory resident
software. Often we use programs for a short time and then never again. However,
these programs often have memory resident components that slow down the
computer. A clean computer is a fast computer. How to clean is computer is the
focus of another article.
In this article the focus is on what makes Windows 7 fast. So the
first step is to measure Windows 7 speed. There are benchmarks and diagnostic
programs that measure performance and speed. While they do a good job, they are
not the measure on what a computer user considers fast. To me fast is responsive.
Windows 7 has a responsive measurement tool called the Windows Experience
Index. It is a measurement scale ranging from 1.0 to 7.9 currently. Newly
purchased computers typically score in the range of 3.4 to 4.5.
To find the Windows Experience Index, click on START, then point
to COMPUTER, click the right mouse button (the other mouse button), and use the
normal mouse click to open PROPERTIES from the bottom of the menu. the overall
rating is displayed smack dab in the middle of the display. A click on the
Windows Experience Index to the right of the overall rating number should
reveal the rating for each of the Windows Experience Index categories.
The Windows Experience Index measures Processor speed, Memory
speed, Graphics card desktop performance speed, graphics card 3D gaming and
business performance, and hard disk transfer rate. It rates the overall
performance of the computer as the lowest score in any of these categories.
Many computers today have quad-core processors running at 2.5 to
3.2 GHz with DDR3 memory. Such systems typically score in the 6.9 to 7.2 range
for CPU and memory speed. Generally, CPU and Memory are not a major
consideration in making a Windows 7 computer fast. My laptop running an Inter
i3 dual core 2.13 Ghz CPU and memory performs in the 5.9 to 6.1 range.
Disk drives in computers are Serial AT Attachment (SATA) drives.
They rotate at 7,200 rpm. This is typically twice the 3,000 rpm at which
automobile engines cruse. Laptop drives may run at 5,400 rpm. High performance
drives operate at 10,000 rpm. So why the focus on rpm speed. A large part of
disk performance is the time it mechanically takes to move the disks read/write
mechanism. Part of that mechanical performance is the rotational speed of the
drive. So 5,400 rpm drives are slower than 7,200 rpm drives. Most SATA drives
have a Windows Experience Index of from 5.6 to 5.9.
What remains is the graphics card performance. That is the area
which makes the Windows experience index run in the 3.4 to 4.5 range.
How do we make our Windows 7 computer more responsive? Changing
processor and memory are costly. They are likely the fastest components
already. Changes there make no sense. With Windows XP, increasing the
computer's memory size from 256 MB or 512 MB to 3 GB or 4 GB noticeably
improves performance. Most Windows 7 computers today come with 3 GB to 6 GB of
memory. Windows 7 64-bit Edition can use more than 6 GB. My computer has 16 GB
of memory. However, application programs mostly are written to use no more than
4 GB or memory. So most of the 16 GB memory is unused. Right now my computer
seems to be using 10 GB of memory. Increasing memory size in a Windows 7
computer is not likely to result in a noticeable improvement in responsiveness.
It is possible to improve responsiveness with a faster disk drive.
This requires disk drive replacement. Two drives can improve performance: 1.
Solid State Drives (no moving parts) and 2. High RPM drives (10,000 rpm). Both
types of drives are expensive with Solid State Drives (SSD) being the most
expensive. Solid State Drives also wear out over time (several years) depending
upon use. The smaller the SSD, the quicker it wears out. SSD are the fastest
drives because there are no mechanical parts.
One disk drive strategy is to get a small 128 MB SSD that only
holds Windows 7 and the application programs and place the remaining data on
another larger SATA drive. The Windows supports the Windows paging files and
temporary file area. These areas are constantly used by Windows to store and
retrieve data while you are working on the computer. Making that storage and
retrieval process faster makes Windows more responsive. Word, Excel, Pictures
and Music files stored on another slower drive do not make the Windows 7
computer less responsive because we expect some delay every time we retrieve
one of those files. My computer uses a 128 GB SSD for Windows. It has a Windows
experience Index of 6.8. All my data is stored on 1TB SATA drives with a
Windows Experience of 5.9. I have not tested 10,000 rpm drives as yet to
determine their Windows Experience Index. The Windows Experience Index is not
published for any drives because it depends in part on the motherboard and CPU
to which the drive is attached.
