I can't imagine that it is either CPU or disk IO on the provider (master). I can however imagine that with various indexes, it can be memory or disk on the subscriber. Building lots of indexes on the fly works better with large shared buffer configs, as they don't even need to be copied in and out of kernel disk buffers.
