Hi, I did not. But I have tried calling Snappy.compress() and decompress() with on-heap and off-heap bytes about 6 months ago. off-heap compress is very fast. But in that experiment, creating off-heap bytes is time-consuming (because in that version, creating new byte array or bytebuffer is very frequent).
I am also interested in the performance of Netty's ByteBuf.
