Too few sampled comments (2) to say how often HN recommends it.?
Why HN links it
HN readers link this blog for its latency and cache performance numbers, cited as evidence that staying inside CPU cache gives large speed gains, and for notes on Linux TCP kernel tuning.
Summarised by Claude from a sample of 2 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

As http://everythingisdata.wordpress.com/2009/10/17/numbers-eve... shows, there is a huge performance benefit when you can stay inside of cache. (Note, those numbers are from Jeff Dean, who is widely lauded within Google for building the infrastructure that…

HN discussionAs said elsewhere.... don't adjust the "richness" controls on your kernel unless there's an actual scalability problem costing you $$. Your special "tweaks" will end up using more memory or slowing performance most of the time. sysctls should be sensible by default on RH (cent/sci/cern/aws) and Ubuntu based kernels. The two most common encountered problems are incast TCP collapse and slow clients. https://everything…
