No, Apache's biggest problem is its architecture that limits quite a few things you can do. Case in point: the farce around mpm_event. It took ages to implement it to solve a central issue Apache always had (i.e. that it could be DoS'd by slow but long-living connections), and even now, it's not exactly in a great state, compared to nginx's async I/O internals.
