Operating Systems Compared
Head-to-head operating system evaluations from production experience: distros, BSDs, and Windows-alternatives compared on support lifecycles, security posture, and 3 a.m. operability — measured, not marketed.

Field notes
Comparisons at Kinetikatech start with the workload and end with the 3 a.m. question: which system can your on-call person actually operate under pressure? Brand loyalty does not survive that test.
We weigh support lifecycles as hard as benchmarks: a platform that ships fewer surprises for ten years often beats a faster one that re-teams you every two.
Security track records matter, but they compare differently at different layers: edge operating systems (OpenBSD-style trust) versus application hosts (Linux ecosystems) versus desktop and identity platforms (Windows family).
Every benchmark figure published here comes with the load shape that produced it — in production, shapes decide winners, and shapes rarely look like synthetic defaults.
