Hmm. Maybe it's easier to send the SM out and deal with the tech fine print by having people read a full write-up from the provided links?

I mainly wish that we could use some relatively safe, apolitical, uncontroversial article for the example.

We could. Or maybe the research or analytics lists list would be better.

But should that block getting the SM out the door?

Obviously we could double check this but I'd wager that Obama's cite count would have trended upward in the last couple years. (so e.g. if we compared older HHVM vs. newer HHVM with constant Obama rev the gains would be more extreme than if we did older HHVM + older Obama vs. newer HHVM + newer Obama)

Anyway, it should be technically feasible to run benchmarks for old software again against the new revisions. In this case the author wasn't actually comparing to past numbers. (I think...) Only generating his own new numbers for a constant rev. And anyway, the comparison to old numbers wouldn't be meaningful (without rerunning them) because hardware's not constant.

I can't imagine a scenario where that's relevant. Does anyone benchmark specific articles over the public internet? vs. running the client on the same local network as the server.

not just manually updated but each entry has its own separate update date??? hrmmm, Obama is listed lower on that list than another article with Obama in title…

P.S. the recently released slow parse logs may be useful for choosing articles to track over time. https://phabricator.wikimedia.org/T98563
