The Kestrel Advantage and Benchmarks
ASP.NET Core utilizes Kestrel, a fast, cross-platform HTTP server built for modern web workloads. This design choice is why the framework consistently achieves top-tier results in independent performance evaluations. According to the widely respected TechEmpower benchmarks, ASP.NET Core performs faster than many popular web frameworks, including those in the Java and Node.js ecosystems .
For a high-traffic e-commerce platform or a global FinTech application, this speed is a game-changer. It means the same workload can be handled with fewer servers, directly reducing operational expenditure. This is the core reason why Benefits Of Asp Net Core To Develop Robust Web Applications are so compelling.
KPI Benchmarks: Performance vs. Cost
When evaluating a framework, decision-makers must look beyond simple Requests Per Second (RPS) and focus on the TCO impact. Here is a simplified view of how ASP.NET Core drives cost efficiency:
