# How fast is H1 Code?

## How fast is H1 Code?

We aim to turn around pull/merge requests as fast as possible. 

* Most detection & validation scanning completes in 2-4 minutes.
* Most code validation complete in less than 2 hours.

In case of emergency, the team should be aware that the *Code service will not block merge*.

n = 21,096 reviews (past 12 months)

Factors that contribute to variety of review turnaround times include:

* The size of the pull/merge request
* The complexity of the code changes
* The expertise required to review the code
