…From changing one line of code!
Intel’s Linux kernel test robot has recently reported a 3888.9 per cent performance improvement in the mainline Linux kernel after Chipzilla geeks changed one line of code.
The test robot highlighted this massive improvement through its “will-it-scale.per_process_ops” scalability test case, running on an Intel Xeon Platinum (Cooper Lake) test server.
According to Phoronix the commit responsible for this performance uplift was labelled with the description term mm, mmap: limit THP alignment of anonymous mappings to PMD-aligned sizes. The patch message confirms that it resolves prior performance regressions and offers substantial improvements in specialised cases.
