Cleaning up VDrift source tree

[BiGBeN87]

Git svn clone should take around 5 h with my internet connection, but I haven't actually timed it. Git gives us a speed up by factor 4, on the equivalent case:

Code:

$ time git clone https://github.com/bigben87/VDrift-Data.git VDrift-Data
Cloning into VDrift-Data...
remote: Counting objects: 25277, done.
remote: Compressing objects: 100% (16627/16627), done.
remote: Total 25277 (delta 8576), reused 25277 (delta 8576)
Receiving objects: 100% (25277/25277), 1.54 GiB | 306 KiB/s, done.
Resolving deltas: 100% (8576/8576), done.

real   70m30.272s
user   4m16.600s
sys    1m18.090s

This translates into shallow clones as follows:

Code:

$ time git clone --depth 1 https://github.com/bigben87/VDrift-Data.git VDrift-Data
Cloning into VDrift-Data...
remote: Counting objects: 12128, done.
remote: Compressing objects: 100% (11709/11709), done.
remote: Total 12128 (delta 443), reused 11895 (delta 375)
Receiving objects: 100% (12128/12128), 1.25 GiB | 736 KiB/s, done.
Resolving deltas: 100% (443/443), done.

real    39m2.372s
user    3m19.890s
sys    1m4.370s

svn checkout for comparison:

Code:

$ time svn checkout -q https://vdrift.svn.sourceforge.net/svnroot/vdrift/vdrift-data VDrift-Data

real    55m15.538s
user    4m18.790s
sys    1m36.670s

So Git/Hub is faster at downloading for end users and patch-only developers, who can use the shallow clone.
