Two Fixes Made Claude Code 15x Faster Per Command on Windows
I ran echo in Claude Code 178 times last week. Median time: 7,395 milliseconds. Not a build. Not a test suite. A command that prints a word and exits. I'd filtered down to commands that do nothing at all, no pipes, no loops, no subshells, because I wanted to know what the tool costs when it isn't doing anything. Claude Code had felt heavy for weeks. I'm on Windows 11 with Claude Code running through Git Bash, and I'd filed the sluggishness under "the model is thinking." It wasn't the model. Two local fixes later, that same echo returns in under half a second and a file read went from 909 ms to 24 ms.
