Single-Board Computers
In my “2026 Journey to Compare Single-Board Computers” (see the posts with tag “JavaOnSingleBoardComputers”), I compare the performance of Java on these boards using the Renaissance Suite. I “wrapped” this benchmark tool in a JBang script to make it easy to run on any SBC with Java 25 and JBang installed. My script, the result collector, and data files are available on GitHub > FDelporte > sbc-java-comparison and the results are visualized here below. To run the script yourself, follow the instructions in the README, or TL/DR:
# Just run the test tool
jbang https://github.com/FDelporte/sbc-java-comparison/raw/main/BenchmarkRunner.java --skip-push
# OR, if you want to contribute your results to the dashboard below:
# 1/ Configure GitHub destination for the report
export GITHUB_TOKEN={ghp_yourtoken}
export BENCH_GITHUB_OWNER={your_github_account} // Default "FDelporte"
export BENCH_GITHUB_REPO={your_fork} // Fork of the tool repository in your account, default "sbc-java-comparison"
export BENCH_GITHUB_BRANCH={your_branch} // Target branch, default "main"
# 2/ Run the test tool
