Why is the website slow to open?

No matter how good our website is , If the web page opens slowly, many users will choose to close or exit , There are many factors to make the website open faster , One of the most common is server performance 、 Network transmission quality 、 Website bandwidth 、DNS Parsing, etc , Now let's analyze some common reasons ：

1、 Reasons for database operation

When a small website carries out many database operations, it may cause the website to open slowly , At this time, what we need to do is to optimize the data .

2、 A large number of large images and FLASH

This problem is known by many people , Image is the most important factor to slow down the Internet speed , If the image is processed, the image space will be reduced to a large extent , Otherwise, many images in the website will occupy our space , This makes the web page slow to open , identical FLASH It's the same thing .

3、 The quality of network transmission is not good

Network transmission quality mainly includes two aspects , They are the network bandwidth quality of the website server and the client , The three major domestic network operation service providers in different bandwidth environments , There will be different degrees of network transmission across the network delay . In this case , Now one of the best solutions is through DNS or CDN This kind can be intelligent and then according to the city where the user is 、 Network line and other aspects of intelligent matching system , Such operation can greatly reduce unnecessary network delay .

4、DNS Parsing time

DNS Parsing takes some time , But many people don't notice this, actually DNS The speed of website parsing is very critical , If the server is attacked during parsing , Then the user's request to visit the website cannot be normally transmitted to the website server .

5、 Server performance

Including the hardware equipment level of server and client , In the same case , If you use a dual core server, it will be stronger , There is no doubt about this , Open the same page , It will be faster , So if it's too slow, you can change the server .

This is probably the reason why web pages are slow to open , If the opening speed is slow once , Then we need to find out the reason , Then deal with it pertinently .
