I was curious so I benchmarked "decrypting" kernelcache.release.n66 on an iPhone 6S and it took about 60 milliseconds to decrypt. It wasn't encrypted in the first place so the decryption results in garbage, but it should be a valid benchmark. The quick boot time with iOS 10 sure is nice, but it isn't because the kernel isn't encrypted.
