Spring Boot 2026: Why Measuring Only Startup Time Is a Trap
The article discusses the limitations of measuring only startup time in Spring Boot applications. It emphasizes that focusing solely on this metric can lead to overlooking significant production costs. A comprehensive lab experiment is presented to illustrate the importance of considering various performance factors beyond just startup time.
- ▪Measuring only startup time is insufficient for making informed architectural decisions in Spring Boot applications.
- ▪The lab experiment compares different modes of Spring Boot performance, including classic JVM and GraalVM Native Image.
- ▪The findings highlight that the trade-off in native mode shifts costs from runtime to build time, which is not captured by startup metrics.

It's the first metric that hits the screen, the number that closes the debate in five minutes.
