The world of web servers is constantly evolving, and each operating system update can have a significant impact on application performance. With this in mind, we’re taking a look at the recent performance of Nginx HTTPS on Linux 6.15. This article highlights a performance regression issue detected during testing on the development kernel. We’ll explore the implications of this on the performance of your web applications. Nginx Server Performance on Linux 6.15 Testing on Nginx, one of the most popular servers for hosting web applications, revealed mixed results with the update to Linux 6.15. While some improvements were noted, others introduced notable regressions, particularly in the handling of HTTPS requests. Performance Improvements It’s important to mention that several tools and benchmarks have shown improvements with version 6.15: Llama.cpp revealed significant improvements in process management.RocksDB
also benefited from the optimizations provided by the new kernel.
Synthetic tools like Schbenchdemonstrated improved kernel scheduler management.
Observed Regressions
However, the element that deserves special attention is the significant performance decline on Nginx. Here are the key takeaways:
- Traditional performance tests showed significant degradation under Linux 6.15
- . Benchmarks conducted with
- OpenJDK and OpenFOAM
also indicated performance issues.
Testing a simple HTTPS server revealed alarming performance losses. Performance Summary Table

| Improved | Improved | 💻 | RocksDB |
| Improved | Improved | Impact on Businesses and Server Optimization | For businesses using |
| Nginx | as an HTTPS server, these regressions can have significant consequences. Slower processing speeds and increased response times can directly impact the user experience, which is crucial in today’s competitive landscape. IT teams must therefore be vigilant and consider optimizations or temporary workarounds. | What to do about these regressions? | Possible approaches to mitigate these regressions include: |
| Rolling back to the stable version of Linux 6.14 if feasible. | Continuous monitoring of kernel updates and associated documentation. | Extensive testing before deployment in the production environment. | Aware of the above, feedback from the community and experienced users would be welcome on this topic.
