In the ever-changing field of operating systems, news regarding performance improvements are often welcome. Recently, Intel highlighted a significant contribution that could transform the user experience: a simple line of code resulted in a stupendous improvement in the performance of the Linux kernel. What are the issues and implications for users? Let’s discover this progress together.
Context of improvement
The Linux kernel, the heart of Linux-based operating systems, is often the subject of much optimization work. The main objective is to increase the ability of systems to handle varied tasks efficiently. This improvement was recorded during testing scalability of the kernel, using servers Intel Xeon Platinum. This type of server is particularly known for its high performance in processing massive data.
Incredible impact on performance
With a gain of 3888.9%, this change was noticed during testing will-it-scale.per_process_ops. This record performance indicates how optimization can transform basic operations into much more efficient tasks. Here are some key points to remember:
- A significant improvement in memory management
- Tests carried out on highly specialized systems
- Potential for reducing wait times in server applications
Technical details of the improvement
The essential change lies in the commit specific made to the kernel which fixed some previous performance regressions. A key element was to establish sizes ofalignment optimal for anonymous memory mappings. By ensuring that the mapping sizes are multiples of the page size, the goal is to benefit from theoptimization offered by large pages THP.
