I didn't really measure this, but intuitively, I'd expect that a one of these operations (parsing/importing one type) would be pretty fast, and that the whole process takes so long simply because performing a very large number of these ops.

My understanding was that the progress increment is designed to be really cheap (writing two pointers) and that it's up to presentation layer to decide a t what frequency to update the UI.

@JDevlieghere — is that perception correct?
