Will system performance decrease when you configure the 404 page?-php Tutorial

Will the system performance decrease when the 404 page is configured? I would like to ask if the system performance decreases when a website starts the 404 page. In other words, the 404 page is configured, after startup, do you need to take up some system performance, such as the system memory, such as the website www.nehosoft.com? do you need to configure the 404 page?

Please give me answers.

Why did no one answer?

The web server has a preset 404 page, which is a static page, you can change your content
If you need to display dynamic content on the 404 page, you need to set the 404 target page and write the relevant program
Whether it is 404 or not, the server always returns a page. Therefore, there is no problem of performance degradation and occupation of additional resources.
