Comparing Kernel System Calls Across Runtimes - Performance Analysis

Explore the performance impact of kernel system calls across different runtimes in this informative video. Utilize strace, a performance measurement tool, to compare the number of system calls made when reading from a file using Node.js, Bun.js, Python, and native C. Delve into the costs associated with kernel mode switches and system calls, gaining valuable insights into runtime efficiency. Follow along as the presenter breaks down the code, analyzes each runtime's performance, and provides a comprehensive summary of the findings. Enhance your understanding of operating system fundamentals and runtime behavior in this practical demonstration of system call analysis.
