+# Git LFS Rate Limits **(FREE SELF)**
+
+[Git LFS (Large File Storage)](../../../topics/git/lfs/index.md) is a Git extension
+for handling large files. If you use Git LFS in your repository, common Git operations
+can generate many Git LFS requests. You can enforce
+[general user and IP rate limits](user_and_ip_rate_limits.md), but you can also
+override the general setting to enforce additional limits on Git LFS requests. This
+override can improve the security and durability of your web application. Aside from
+precedence, this configuration provides the same features as the general user and IP
+rate limits.
+
+## Configure Git LFS rate limits
+
+Git LFS rate limits are disabled by default. If enabled and configured, these limits
+supersede the [general user and IP rate limits](user_and_ip_rate_limits.md):
+
+1. On the top bar, select **Menu >** **{admin}** **Admin**.
+1. On the left sidebar, select **Settings > Network**.
+1. Expand **Git LFS Rate Limits**.
+1. Select **Enable authenticated Git LFS request rate limit**.
+1. Enter a value for **Max authenticated Git LFS requests per period per user**.
+1. Enter a value for **Authenticated Git LFS rate limit period in seconds**.
+1. Select **Save changes**.
