Is 3.2Mb a typical kernel size for small systems? It sounds large.
0.24 seconds booting speedup sounds pretty thin. Adding a new decompression format will introduce more configuration/build/deployment complexities. How do we justify this?
Did anyone look into just speeding up the gzip decompressor?
