Always consider how your app affects the performance of large instances. These are instances that host large data sets and sustain a significant amount of traffic.
Ensure that you have appropriate indexes set up on all tables introduced by your feature or app. Wherever possible, filter data in database queries, rather than relying on in-app filtering, as the latter may require loading and discarding lots of data.
Finally, always test your feature or app on a Data Center instance with a large data set. The following subsections provide guidelines on what we consider a large instance for each product.
A Bitbucket instance with these dimensions is considered large:
| Dimension | Baseline |
| General | |
| Users | 15,000 |
| Groups | 5,000 |
| Projects | 30,000 |
| Repositories | 75,000 |
| Pull requests | |
| Open | 100,000 |
| Closed | 5,000,000 |
| Comments on pull requests | 10,000,000 |
| Nodes | 5 |
| Continuous load for the baseline in the performance smoke test | |
| Clone | 8 concurrent; 30/minute |
| Fetch | 8 concurrent; 800/minute |
| Push | 8 concurrent; 10/minute |

A Confluence instance with these dimensions is considered large:
| Dimension | Baseline |
| Users | 100,000 |
| Groups | 15,000 |
| Group memberships per user | 1,500 (20 average) |
| Spaces | 5,000 |
| Pages | 1,000,000 |
| Pages per space | 10,000 |
| Comments per page | 100 |

| Attachments per page | 1,000 (10 average) |
| Global permissions | 200 |
| Space permissions | 200 |
| Page permissions | 200 |
| Application nodes | 4 |
| Traffic | 700,000 HTTP calls per hour |
Some of these dimensions use the upper limit of the content and traffic metrics for large instances in Confluence Data Center load profiles.
