CodSpeed v5 is out, with two big changes to how we measure your code.
First, cycle estimation: every instruction is now weighted by its measured cost on real CPUs, cache misses included. A `div` no longer counts the same as a `mov`.

![[codspeed benchmarking comment saying that one PR that rewrites some of the core logic in rust will increase performance across our benchmarks by 37%. each of the tests are a processing graph run in different ways - a synchronous runner just calls the graph... synchronously.. in order, and a ZMQ runner is a multiprocess runner that runs each node concurrently, swapping events over zeromq. i figure the details are probably not important to anyone but me, but if you are curious about the actual numbers in the table, HTML is probably easier for screenreaders and tables than i can render here, so that's over here: https://github.com/miniscope/noob/pull/243#issuecomment-4977387758 ]](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:22yyehc52vyozjdxuvhlfwh6/bafkreihi3skfp4kj5xk4k766kjrvdada3kiszwrysivly4hiuymz4dclxe)
![[benchmarks that i ran locally on just the part that was swapped out - regular graphs are scheduled 4-5x faster than before, and large graphs are more like 10x]](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:22yyehc52vyozjdxuvhlfwh6/bafkreihqznkraz544txleyxp2bjnf2swjgmpwucm7vd23llao4oanzohfy)

@glyph I’ve never heard of this website and assumed “codspeed” was a typo of “codespeed” until I saw that, no, that’s really the name? And it has a rabbit instead of a fish for the logo???
