So almost a year ago, there was this: https://lobste.rs/s/51d5kg/new_tag_suggestion_performance
but nothing came of it (if there’s some other process that I’m not aware of, let me know!). I’m taking a second swing at it since over the past few weeks I’ve either submitted or seen stories that would have easily fit the “performance” tag. The only other tag that I’ve seen that’s related is “scaling”, but that’s somewhat orthogonal to “performance” (thought they can be related).
Just a search for “performance” shows 4,888 stories and while not all of them would warrant the tag, it’s one that’d certainly help me look for and tag stories that I submit.
