* There are some situations where the Kotlin DSL is slower. First use, on clean checkouts or ephemeral CI agents for example, link:{gradle-issues}15886[are known to be slower].
The same applies to the scenario in which something in the _buildSrc_ directory changes, which invalidates build-script caching.

<3> The Kotlin build script applies the Groovy script

== Limitations

* The Kotlin DSL is link:{gradle-issues}15886[known to be slower than the Groovy DSL] on first use, for example with clean checkouts or on ephemeral continuous integration agents.
Changing something in the _buildSrc_ directory also has an impact as it invalidates build-script caching.
The main reason for this is the slower script compilation for Kotlin DSL.
