Supercharge your Git experience in VS
Have you experienced delays when viewing your Git repository or branch history in Visual Studio? Have you run a network command like force-push and had to wait for the operation to complete? Your Git repository may be having performance issues due to its large size. We are happy to integrate a relatively new Git feature called the commit graph which leads to improving the performance of your Git operations and significantly improving performance in Visual Studio.
Once you are on the latest preview version of Visual Studio (17.2 Preview 3 or later), Visual Studio will automatically show the following notification where you can choose to enable the commit graph.
Alternatively, you could manually enable the commit-graph by going to Git > Settings > Enable commit graph for better Git performance.
What happens when you enable the commit graph?
When the commit graph is enabled, a commit graph file gets generated in your repository which then is used to quickly parse and sort your commits. The commit graph file also includes extra information to help avoid parsing commits. Generating the commit graph is a background operation that could take several seconds up to couple of minutes depending on the size of your repository. It is also a blocking Git operation that will block you from performing other Git operations in Visual Studio like Fetch or Pull. View this blog to read more about how the commit graph works.
When should you consider running the commit graph?
You will see most of the value of the commit graph right after you run it for the first time. Visual Studio will only show the commit graph notification when it is not enabled, and when Visual Studio predicts that running the commit graph could enhance performance.
How to manually run the commit graph
If you did not receive the notification, you can also choose to manually re-run the commit graph at any time if you have already enabled it in Visual Studio by using the following command line or by disabling and enabling the commit graph in our Git settings Git > Settings > Enable commit graph for better Git performance.
