Problem using git

Hello The kernel tar file from "www.kernel.org" is around 70MB. but when i want to download the kernel using git it seems it's really huge. git shows 1% for 25MB. Is it how it should be or am i missing something? the git command i used is this: "git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git"
