Go programs are slow compared to C++, the compiler optimises for its own speed and simplicity rather than fast output binaries. But there are big architectural differences too. Borg can split its master across multiple machines for example. The scheduler is a very tightly optimised piece of code. Borg clusters are managed by a central, dedicated specially trained team so there's basically no limit to the operational complexity that a Borg cluster can take on as long as they're all consistent - which they are.
