Torvalds had spent 18 months running a broken version of his own fix for the page-cache reference-counting bottleneck, while other developers had encountered problems with their approaches. The new patches eliminate folio reference-count operations from a common buffered-read path, although Torvalds warned that the benchmark gains would be considerably smaller in real-world workloads.

You know how in star trek or other shows with scripts, how the writers used to just put like or something

They need to add an analogy in there...

"The problem is with the folio reference-count operations from a common buffered-read path"

"Of course! It's just like putting too much air in a balloon!"

Yeah so then I swapped the flux combobulator with the drago-fleefloo-spectromodulator and we're up to warp speed again. Thank you, Captain!
