How do different operating systems and microarchitectures affect the end user…

SemiAnalysis observed substantially different waiting times for shell commands issued by Anthropic's Claude Code across operating systems. Its published chart covers 662,654 Bash calls and gives median return times of 1.27 seconds on Linux and 4.00 seconds on Windows. The measurement includes command execution and client overhead, making it relevant to the pauses an agent experiences between actions. It is an observational comparison of calls, however, and does not establish that changing operating systems alone would triple the speed of a complete coding task.
