How to solve the slow running of windows system? in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and easy way.

If we can find out what data was written, maybe the problem can be solved, so after scanning the hard disk with treesize, we found that the temporary folder under the administrator user is as high as 2G. And are web pages, js, pictures and other small files, it is due to this reason, resulting in the system.

The spare machine responsible for collecting is suddenly very stuck after landing recently. Use the task manager to find that memory and cpu are very free, so use performance monitoring to monitor hard drives, memory and cpu

In general, performance monitors only look at three metrics

Pages/sec: generally speaking, a few dozen indicates that there is a bottleneck in memory. The specific indicator refers to the speed at which hard pages are read from or written to disk in order to solve hard page errors. This counter is the main indicator that can display errors in the type of system-wide delay. It is the sum of memory\\ pagesinput/sec and memory\\ pagesoutput/sec. Is calculated with the number of pages so that it can be compared with other page counts such as: memory\\ pagefaults/sec without conversion, this value includes pages retrieved in non-cache-mapped memory files in the file system cache (usually requested by the application) to satisfy the error. In general, if the pages/sec is consistently higher than a few hundred, then you should further study the page exchange activity.

The percentage of% processortime:cpu usage should generally be less than 80%, and more than 80% means that cpu is not effective. The specific indicator refers to the percentage of time that the processor spends executing non-idle threads. The method of calculation is to measure the time of non-idle thread activity in the sample interval and subtract the value from the sample interval. Each processor has an idle thread that consumes cycles when there are no other threads to run. This counter is the main illustrator of processor activity, showing the average percentage of busy hours observed during the sample interval. This value is calculated using 100% minus the time the service is inactive. Generally speaking, the average activity compliance of cpu should be less than 80%, and more than 80% indicates that the processing capacity of cpu has reached its limit.

Avg.diskqueuelength to see how many hard drives you have, no more than 1.5 times the number of hard drives, according to the buton of the application, more than means that there is a bottleneck in reading and writing the hard disk. The average number of read and write requests (for the selected disks queued in the instance interval).

After checking, it is found that the avg.diskqueuelength is as high as a little bit, and the pagesec is also on the high side, so it is suspected that some programs are frequently reading and writing and exchanging data in memory, so then we need to find out the programs that use the hard disk.

There are two ways to find out which programs are using the hard disk. The first way is to use specialized software, such as ip radar, which can visually see how busy the hard disk is and which programs are reading and writing to the hard disk.

If all of a sudden, there is no time to install special software, you can also directly use the task manager that comes with windows to find programs that frequently write to the hard disk. The method is to call up the task manager, click View, select the column, read iUniqo, write iGram0, and check other ticks. You can see which programs are reading and writing to the hard disk in the accident.

When I was using ip radar, I found that it was the system program that read and write the hard disk. Is it poisoning? At this time, check ip radar found that system program is constantly writing a large amount of data, up to hundreds of meters, so much data accumulated, the signs of occupation in the hard disk should be more obvious, if you can find out what data is written, maybe the problem can be solved, so use treesize to scan the hard disk.

After scanning, it is found that the temporary folder under administrator users is as high as 2g. And they are all web pages, js, pictures and other small files. It turns out that for this reason, the system runs slowly. For so many temporary files, it is very slow to use cleaning tools such as 360. the final solution is to use the dos rd command, which is as follows

Rd/s/q "c:\ documentsandsettings\ administrator\ localsettings\ temporaryinternetfiles"

Rd/s/q "c:\ documentsandsettings\ administrator\ localsettings\ temp"

At the same time, save the command as bat, join the planned task of the system, and record the solution process as follows. I hope that if friends encounter similar situations in the future, this article can provide some help.

This is the answer to the problem of how to solve the slow operation of the windows system. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
