Hierarchical CA is the best approach when there are binary features or a mix of features types. But 20000x20000 proximity matrix is too big for it. So you simply do the clustering on random subsamples of it (of size, say, 1000 objects). If there are clear clusters in your data, they must show in each subsample.
