 * When the system wall clock jumps back in time, this clock will effectively slow down until it is back in sync.
 * All syncing timestamps will be the same as the previously issued timestamp.
 * The rate by which this clock slows, and therefore the time it takes to resync,
 * is determined by how frequently the clock is read.
 * If timestamps are only requested at a rate greater than the sync interval,

Use the Profiler to produce build scans. Or combine it with method profilers like JProfiler and YourKit.
These profilers can help you find inefficient algorithms in custom plugins.
If you find that something in Gradle itself slows down your build, don't hesitate to send a profiler snapshot to ******@****.***.

== Performance categories

Both build scans and local profile reports break down build execution into the same categories.

====

WARNING: Forking a VM is an expensive operation. Setting too small a value here slows down testing.

==== Disable reports

Gradle automatically creates test reports regardless of whether you want to look at them.
That report generation slows down the overall build. You may not need reports if:

* you only care if the tests succeeded (rather than why)
