How to speed up nginx performance

Open gzip

Configuration

# 开启gzip
gzip on;
# 启用gzip压缩的最小文件，小于设置值的文件将不会压缩
gzip_min_length 1k;
# gzip 压缩级别，1-10，数字越大压缩的越好，也越占用cpu时间，后面会有详细说明
gzip_comp_level 2;
# 进行压缩的文件类型。javascript有多种形式。其中的值可以在 mime.types 文件中找到。
gzip_types text/plain application/javascript application/x-javascript text/css application/xml text/javascript application/x-httpd-php image/jpeg image/gif image/png;
# 是否在http header中添加vary: accept-encoding，建议开启
gzip_vary on;
# 禁用ie 6 gzip
gzip_disable "msie [1-6]\.";

gzip_comp_level parameter

For reasonable values ​​of gzip_comp_level, please refer to the figure below. From

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;
}

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;
}

Enable gzip

Only need to enable gzip for ttf, otf and svg fonts. The effect of gzip compression on other font formats is not obvious.

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

The compression effect of various font types can be referred to the following test results:

It can be seen that the gzip compression effect of woff and eot is not good.

Font summary

Extension	Whether to compress	content-type
.eot	No	application/vnd.ms-fontobject
.ttf	is	font/ttf
.otf	is	font/opentype
