Experiments covered

From 2020 / H1

In the early of 2020 I run the following benchmarks locally, quite manually but I've kept the datasets. These were the examples and datasets I've used in my public talks about Gradle Profiler.

Building Kotlin MPP with different JDKs

• Target : SdkSearch
• Datasets :conferences/sdksearch-kmpp-different-jdks
• Goal : demonstrate that builds don't improve when building Kotlin MPP with JDK11 instead of JDK8

Bumping Gradle + AGP version

• Target : IOSched
• Datasets :conferences/iosched-updating-gradle-agp
• Goal : demonstrate that bumping Gradle + AGP from 3.4.x to 3.6.x brings a lot of improvement in the Android build

From 2020 / H2

Building Kotlin MPP with different JDKs

• Target : SdkSearch
• Datasets :sdksearch-kmpp-different-jdks
• Goal : demonstrate that builds don't improve when building Kotlin MPP with JDK11 instead of JDK8

Running the experiment and generating data by yourself (OSX only)

1. Make sure you have git, gradle-profiler, jdk8 and jdk11 installed
2. Run the companion script

cd sdksearch-kmpp-different-jdks
./run.sh

Bumping Gradle + AGP version

• Target : Sunflower
• Datasets :sunflower-agp-bump-4.0.x
• Goal : demonstrate that bumping Gradle + AGP from 3.6.x to 4.0x DOES NOT bring improvements in the Android build at all

Running the experiment and generating data by yourself (OSX only)

1. Make sure you have git, gradle-profiler and jdk8 installed
2. Run the companion script

cd sunflower-agp-bump-4.0.x
./run.sh
