i've been hitting some slowdowns with my panda scripts lately it's not just one thing - it feels like everything is taking longer. i mean seriously: four-hour pipelines that used to take twenty minutes, jobs timing out on data sets from six months ago. and the worst part? sometimes you look at your code "this should work" but boom - slow as molasses.
most of these issues are stemming back to row-level iteration in python. it's a common pitfall that can really drag down performance, even when everything looks correct on paper ⚡
anyone else running into similar snags or have any tips for speeding things up? i'm all ears!
