```
file    size    gzip size     file
js      217.4K  217.4K        js/scripts-0004.min.js
css     53.3K   53.3K         css/style-0004.min.css

```

why does `gzip` return files with the same size?

do they need additional packages for `gzip` on `ubuntu 12.04 + python + nginx server`.

nginx.conf

http {

```
##
# Gzip Settings
##

gzip on;
gzip_disable "msie6";

gzip_vary on;
gzip_proxied any;
gzip_comp_level 6;
gzip_buffers 16 8k;
gzip_http_version 1.1;
gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;

```

}

```
