How to make your Executable Binaries smaller

There are some good executable compressor, for example UPX. Compressor could reduce your executable size into smaller one, for example a Go compiler always produce a quite big binary, we could reduce it using goupx (requires Go installed), that you can install using this command:

yaourt --needed --noconfirm -S --force upx
go get -u -v github.com/pwaller/goupx

Then you could compress using this command:

$ goupx THE_EXE_FILE

Packed 1 file.

The result is quite good (22-33%), your program will load faster on slow disk. One drawback about executable compressor is multiple instance/execution would use more RAM, since their code won't be shared.
