You can do "profile-guided optimizations" in C++ as well. It's easier to exploit CPU capabilities (e.g. AVX) if you run the compiler on the client side, but once again compilers can do the same. The latency requirements prevent some of the more aggressive and time consuming optimizations from being attempted.
