Reducers can perform fewer allocations than lazy seqs, but that does not automatically translate into a big speed difference, especially with your trivial example.
Try comparing chained lazy seq ops (map, mapcat, filter, take, drop, etc) to an equivalent chain of reducer calls: you may see a more pronounced speed difference. Reducers can also be foldable (thus parallel) if the source data structure supports it but are not so automatically. Try r/foldcat or r/fold to possibly see pmap speeds. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
