Seven evaluations with Vista! Windows 7 is not fast

With the PDC 2008 (Microsoft Professional Developers) conference, Microsoft first revealed the details of Windows 7 to the public. For a time, all kinds of news about this operating system began to fly like a piece of paper. Among them, there is news that the new version of Windows 7 will greatly surpass Vista in terms of performance.

So, is this really the case?

In the end, will Windows 7 be strong?

Can't help the curiosity in my heart, the author started this experience today.

I. Evaluation Environment

Figure 1 Evaluation Environment

In order to ensure fair and accurate test results, we have a total of two sets of operations for the test machine. system. The leaked version of Windows 7 Pre-Beta Build 6801 and the official version of Windows Vista SP1. Prior to the official test, both were automatically updated to install all high-priority patches. At the same time, both systems have turned on desktop Aero effects. During the entire evaluation process, no other third-party programs were installed except for the necessary testing tools.

Second, basic performance evaluation

1. Open and close speed comparison

[Test method] In daily operation, the speed of opening and closing can often give people the most intuitive Performance feeling. In this test, we will use the stopwatch to measure the specific opening and closing times of the two operating systems. At the same time, in order to minimize the error, all data will be tested three times, and the average of three times is included in the table.

* When booting: Start with the computer entering the multi-system menu until the desktop icon is displayed, and the metering time is used.

* When shutting down: Start by clicking the shutdown menu until the computer is completely powered off, and the metering is turned off.

The test results will come out soon, and the new version of Windows 7 does not bring us the expectation. Speed ​​up experience. On the contrary, the overall use is longer than the older version of Vista. Fortunately, from a numerical perspective, the gap between the two is not obvious. If you put it in the actual application environment, you should still not feel it.

2. Sleep, recovery time comparison

[Test method] System hibernation can help users start the system faster, and can also save various unclosed programs. Therefore, in this test, we will separately "free state sleep" for both operating systems, "idle state recovery", "15 window sleep", "15 window recovery" state statistics. At the same time, in order to minimize the errors that may occur in the test, all data will be tested three times and the average of three times will be included in the table.

Figure 3 Sleep, recovery time comparison (unit: second)

Like the switch test, Windows 7 is also not in the sleep and recovery test, accounting for any Cheap. Not only is each data less than Vista, it is 5-10 seconds behind. Moreover, the overall time has also greatly exceeded the normal opening and closing time. At the same time, from the test data, if there are a large number of unclosed windows before hibernation, it will have a greater impact on the system's sleep and recovery. However, the impact of the two versions of the operating system is basically the same.

3. File Copy Performance

[Test Method] Due to different file copy modes, the file copy performance between the two versions of the operating system is different. In this test, we will complete the performance test of the hard disk and U disk, respectively. Among them, the hard disk test will adopt the same scheme of the same partition and cross partition. For the U disk test, the U disk is used to transfer the hard disk and the hard disk to the U disk.

Figure 5 U disk file copy comparison (unit: second)

From the final results, there is not much difference in the file copy performance between the two versions of the operating system. But overall, Vista is still stronger. Earlier, we have learned that Vista SP1 is exactly the same as XP's "buffer I/O mode". Therefore, it is inferred that the new version of Windows 7, should also be based on this model.

4. LAN transmission performance comparison

[Test method] To verify the difference in LAN file transfer performance between different operating systems. We first built a simple 100 Mbps wired peer-to-peer network platform using switches. Then, through the Windows file sharing mechanism, file transfer is performed with a secondary computer with WinXP SP3 installed. To ensure fair and accurate test results, the auxiliary computer does not have any anti-virus software and firewall software installed. At the same time, XP's own firewall system will also be turned off during testing.

Note: Both systems will remain in the default firewall settings.
