That's not as odd as it seems: there is *always* a signal, even if that signal happens to be silence, and while the actual processing parameters depend on signal level, the algorithm itself is always the same. It could be optimised for 'silence' by removing the per-sample interpolation of the filter parameters when those are static, but I don't think that would be worth the effort. That said, 6% seems too much.
