Fair enough. It might not scale down that well, especially since on low-memory systems you often worry about CPU usage and power usage as well. But Go uses a lot less memory to begin with, so the default GOGC value of 100% (half of application memory used, half free) will still be less than a similar Java program, even ignoring that Java also needs a heap larger than the allocated size to get good performance.
