How much disk space does your libra binaries take?

After building rust client and compiler, the target/debug folder on my computer is 9.9GB. And the client binary is ~400MB.

I’m new to rust, but this seems ridiculous to me. Golang libra client with almost same function is only ~14MB.

Is this due to compiling in debug mode, or is my rust configuration problematic? Does anyone compiled in release mode?
