To our surprise, the study shows that the performance of many core operations of Linux has worsened or fluctuated significantly over the years. For example, the select system call is 100% slower than it was just two years ago. An in-depth analysis shows that over the past seven years, core kernel subsystems have been forced to accommodate an increasing number of security enhancements and new features. These additions steadily add overhead to core kernel operations but also frequently introduce extreme slowdowns of more than 100%.
Should we be concerned, @Linux ?
Here’s a link to the abstract and the full text of the published study.
