While the statement C++ code runs ~10x faster than blueprints is true, bear in mind that in most simple cases it really doesn’t matter. If you have your blueprints doing simple tasks that end up taking 0.01ms, then turning them into C++ is a huge waste of time. Big time-consuming tasks that take > 0.5ms, like pathfinding algorithms ought to be in C++, but simple gameplay logic and other things Blueprints are commonly used for are fine the way they are.
