+== Speedup Git on Windows ==
+
+Git tends to be rather slow for repositories with a huge amount of files on Windows.
+One way to deal with that is to use a sparse-checkout, to "ignore" certain files.
+The ''LayoutTests'' directory is certainly a good candidate, if you currently do not need these files.
+A sparse-checkout uses a config file (''.git/info/sparse-checkout'') to determine if a file should be checked out or not.
+Files mentioned in the config file will be part of the checkout.
+Files not mentioned in the config file will be ignored.
+There is also a syntax to invert this logic, but it is currently not working well with directories.
+
+  1. Create a ''sparse-checkout'' file with all the files/directories that you need. You can use the following command in git-bash to create such a file that will ignore the ''LayoutTests'' directory.
+{{{
+ cd WebKit
+ ls -a | grep ".[a-zA-Z]" | grep -Ev "^.git|LayoutTests$" > .git/info/sparse-checkout
+}}}
+  2. Update the git tree cache
+{{{
+ git read-tree -m -u HEAD
+}}}
+
+  2. Check which files have been excluded
+{{{
+ git ls-files -v | grep ^S
+}}}
