After the website is slow and apache is restarted

After the website slows down and restarts apache, the website slows down and restarts apache. after the restart, the website slows down again for a period of time. the cpu and memory of the server are both normal and rarely used, and the ping response is fast, generally, it takes more than 10 ms, but it is slow to open the website. The most recent problem has occurred. could you please check this problem? well, if you don't want to answer this question, it will be normal to check if the website is slow and restart apache?

------ Solution --------------------
In fact, I have also met you. after a while, I just want to know why.
------ Solution --------------------
The key lies in Rarely used
Because it is rarely used, the memory required by apache is squeezed onto the hard disk, and even the required dynamic link library is detached from the memory.
When it is used, it is loaded from the hard disk, or even dynamic link library. Of course it will be slow.
------ Solution --------------------
Normal After apache is restarted
The root cause is apache.

Try again.

Boss, this explanation seems inappropriate. if it is the reason you mentioned, it should be able to recover to normal after several visits using a browser. I am afraid the landlord will not raise this question.

How is the number of apache connections? Enough Bandwidth

First, check whether the problem is apache. Will the resolution of the url become slower? can it be better to restart the machine?
------ Solution --------------------
After the restart, everything works normally, indicating that there is no problem with apache or anything, and it slows down in a short time. This problem occurs. you are troubleshooting it slowly ,,,
This problem means it hurts...
------ Solution --------------------
Win or linux?
------ Solution --------------------
It really hurts...

Is it related to the program? If the program is not well written, it will make apache very tired... Even if the traffic volume is small
