Benchmarking Resource Utilization: Quarkus Native vs. Spring Boot Native

[porunov]

Hi everyone,

I'm currently researching resource utilization and benchmarking modern Java frameworks, specifically comparing Quarkus Native and Spring Boot Native. In my search, I found a recent study (March 31, 2025, link) that presents some interesting findings:

• Quarkus Native: Smaller artifact size, faster build time;
• Spring Boot Native: Lower RAM usage and higher request throughput (5865.02 requests per second vs. 4932.04 for Quarkus Native, with average RAM usage of 115 MB for Spring Boot Native compared to 379 MB for Quarkus Native).

This is particularly surprising because earlier research, such as a 2022 study (link), suggested that Quarkus Native would have an advantage in resource utilization over Spring Boot Native.

However, I do have a few concerns about the methodology in the latest study:

• Methodology Clarity: The post did not include the benchmark code or details on how the tests were conducted.
• Conflicting Statements: There’s an inconsistency where the study mentions that Spring Boot Native has a lower memory footprint yet also notes “higher cloud infrastructure costs due to memory footprint.” This contradiction makes it challenging to interpret the results.

Has anyone conducted similar benchmarks in 2025 or have updated research on this topic? I’d love to see sample projects, benchmark code, or even just your personal findings to help validate or challenge these results.

Thanks in advance for sharing your insights!
