Well, if your updates come in batches, you could still see significant benefits by storing the persistent map in an atom and using transients to perform the batch updates within a single call to swap!. Otherwise, I guess they might not be suitable for your purpose (yet -- we'll see what happens with pods). -Jason -- You received this message because you are subscribed to the Google Groups "Clojure" group.
