it definitely could take a while on a huge data structure, but such work is generally CPU bound, not i/o bound. If your coroutine-based service ends up CPU bound, there's not much you can do other than (1) optimize hot spots or (2) add more cores -- either of which is still usually a step up over "too many threads = kernel sadness".
