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? > +#ifdef STATIC What is this STATIC thing for? -- To unsubscribe from this list: send the line "unsubscribe linux-embedded" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
