The article details how the authors significantly reduced the size of their Go Agent binaries—by up to 77%—through a combination of techniques. Primarily, they focused on using UPX compression, stripping debug information, and leveraging a more efficient build process with optimized linker flags. These changes resulted in smaller, faster-to-deploy agents with minimal performance impact.
