It can be seen from the figure that the effect is not very obvious when gzip_comp_level is greater than 2. So you can set the value to 1 or 2.

Enable caching

Configuration

location ~* ^.+\.(ico|gif|jpg|jpeg|png)$ { 
    access_log  off; 
    expires   30d;
}
location ~* ^.+\.(css|js|txt|xml|swf|wav)$ {
  access_log  off;
  expires   24h;
}
location ~* ^.+\.(html|htm)$ {
    expires   1h;
}
Copy after login

The cache time can be modified as needed.

About fonts
Enabling caching for static resources can reduce the consumption of server bandwidth, especially when using fonts in css. At the same time, combined with gzip compression, it can greatly reduce the cost of downloading fonts. Bandwidth impact.

Set font cache

It should be noted that there are many font formats, and it is necessary to set cache for all font formats.

location ~* ^.+\.(eot|ttf|otf|woff|svg)$ {
    access_log  off;
    expires max;
}
Copy after login

gzip_types font/ttf font/otf image/svg+xml
