An increased maximum increases resource +consumption of your instance. Keep this in mind when adjusting the maximum. + +To speed the loading time of merge request views and branch comparison views +on your instance, you can configure three instance-level maximum values for diffs: + +| Value | Definition | Default value | Maximum value | +| ----- | ---------- | :-----------: | :-----------: | +| **Maximum diff patch size** | The total size, in bytes, of the entire diff. | 200 KB | 500 KB | +| **Maximum diff files** | The total number of files changed in a diff. | 1000 | 3000 | +| **Maximum diff lines** | The total number of lines changed in a diff. | 50,000 | 100,000 | + +When a diff reaches 10% of any of these values, the files are shown in a +collapsed view, with a link to expand the diff. Diffs that exceed any of the +set values are presented as **Too large** are cannot be expanded in the UI. + +To configure these values: + +1. On the left sidebar, expand the top-most chevron (**{chevron-down}**). +1. Select **Admin Area**. +1. Select **Settings > General**. +1. Expand **Diff limits**. +1.

If you know beforehand what issues +one might have when setting this up, or when something is changed, or on upgrading, it's +important to describe those, too. Think of things that may go wrong and include them here. +This is important to minimize requests for support, and to avoid doc comments with +questions that you know someone might ask. + +Each scenario can be a third-level heading, for example `### Getting error message X`. +If you have none to add when creating a doc, leave this section in place +but commented out to help encourage others to add to it in the future. --> |
