English is not my own language and maybe I have expressed myself wrong. Sorry. 8^) With out-performing I wanted to say: "out of an acceptable performance", "bad performing". I say this because ALL of it's buffer allocation scheme is based on the kernel malloc()/free() functions, and not on a pre-allocated buffer pool. Maybe STREAMS implementation could be more easily implemented if we noted the similarities with the BSD scheme, since both derive from the eighth edition streams.
