    CodSpeed v5 is out, now with more accurate cycle estimation and the ability to exclude allocators from the simulated execution ⚡

    CodSpeed v5 is out, with two big changes to how we measure your code. First, cycle estimation. Until now, every instruction was charged the same cost, but a `div` is ~25x more expensive than a `mov` on real hardware. We patched Callgrind to emit per-instruction metadata and

    “op read” (@1Password cli) takes almost 1s to read a secret. Apple’s “security” is sub 100ms. Is there some trick to make 1Password faster (on an M4 Max machine?!) so I can actually use it in scripts? To be honest Apple’s 90ms for a secret retrieval is questionable too.

    This is exactly what we had in mind building our MCP server. Your agent gets the same level of details you can get by browsing profiling data and finally have insights on what and how to optimize

    Performance work with @codspeedhq's MCP server feels like a cheat. Instead of stumbling round in the dark with a machete, attempting to hack at random patches of code, Fable and I are a sniper - the MCP tells me which code is slow, we figure out how to make it fast. Rinse.

    CodSpeed can now optimize your code for you! The agent runs benchmarks with CPU simulation, generates profiling data, and iterates: edit, measure, compare. It stops when it finds something measurable. You get the diff + a PR.
