Hello everyone,

I followed the _Building Beats from the Source_ documentation in the Beats repository. After building, I ended up with a Filebeat binary around 90 MB, but the Filebeat binary downloaded from GitHub is about 150 MB. Am I missing some essential steps?

Go version: 1.19.4  
OS: Linux/amd64  
Version: 8.9.0

Official download page: [Filebeat 8.9.0 | Elastic](https://www.elastic.co/downloads/past-releases/filebeat-8-9-0)  
Linux x86\_64

My build result:

> -rwxr-xr-x 1 root root 101710152 Oct 28 16:49 filebeat

Result from extracting filebeat-8.9.0-linux-x86\_64.tar:

> -rwxr-xr-x 1 root root 158869624 Oct 21 15:01 filebeat

build shell

```shell
# build
make mage

cd filebeat
mage build

```
