Polling configuration
The GitLab UI polls for updates for different resources (issue notes, issue titles, pipeline statuses, etc.) on a schedule appropriate to the resource.
In "Application settings -> Real-time features" you can configure "Polling interval multiplier". This multiplier is applied to all resources at once, and decimal values are supported. For the sake of the examples below, we will say that issue notes poll every 2 seconds, and issue titles poll every 5 seconds; these are not the actual values.
- 1 is the default, and recommended for most installations. (Issue notes poll every 2 seconds, and issue titles poll every 5 seconds.)
- 0 will disable UI polling completely. (On the next poll, clients will stop polling for updates.)
- A value greater than 1 will slow polling down. If you see issues with database load from lots of clients polling for updates, increasing the multiplier from 1 can be a good compromise, rather than disabling polling completely. (For example: If this is set to 2, then issue notes poll every 4 seconds, and issue titles poll every 10 seconds.)
- A value between 0 and 1 will make the UI poll more frequently (so updates will show in other sessions faster), but is not recommended. 1 should be fast enough. (For example, if this is set to 0.5, then issue notes poll every 1 second, and issue titles poll every 2.5 seconds.)
