# Triggering biological age acceleration computations

Since biological age acceleration computations are resource-intensive, we don't start them automatically on each new sample batch received. There are two options on how to trigger them:

1. Biological age accelerations will be calculated automatically 5 minutes after receiving the last batch with a user's data.
2. You can manually trigger these computations when the last batch is sent by calling `/bioage/calculate`.
