The presentation discusses a family of simple performance models that I developed over the last 20 years — originally in support of processor and system design at SGI (1996-1999), IBM (1999-2005), and AMD (2006-2008), but more recently in support of system procurements at The Texas Advanced Computing Center (TACC) (2009-present).

In 2009 at Velocity–the annual performance optimization conference–there was a flurry of information released by companies that clearly demonstrated how performance effects key business objectives. Shopzilla presented information detailing how they were able to speed up their site from 4-6 seconds to 1.5 21% less searches.

I wrote an ftrace toolkit, [perf-tools], and the article [Ftrace: the hidden light switch]. - **perf**: since 2009, this started as a PMC profiler but can do tracing now as well, usually in a dump-and-post-process style. It's fast, but limited in places, and usually only suited as a single-user tool (there are workarounds).

At the same time, they open a door to lots of concepts that might be overwhelming: PRPL, RAIL, Paint Timing API, TTI, HTTP/2, Speed Index, Priority Hints and more … Why Performance doesn’t get Prioritized Web performance at organizations is a real challenge. In fact, Stockholm was the first city in installing 4G back in 2009.
