A concise expression meaning "of adequate performance" without stretching to "high-performance" (especially since High Performance Computing has a specific meaning of its own). Unfortunately, in the modern language of hyperbole, terms like "adequate" and "acceptable" have negative connotations along the lines of "not really good enough but better than nothing". So, we, as an industry, have invented a jargon word "performant" to express the idea that a thing has a level of performance sufficient that you don't need to worry about it and can look for optimisations elsewhere in your system.
The JVM is performant.

Term for someone in the entertainment industry that people will pay to go see or watch on the screen, despite the fact that said person can't really sing, play music, act or do anything else noteworthy. Because they don't really sing, perform music or act, they can't legitimately be called singers, musicians or actors. 'Performer' is a nice catch-all term for such people that doesn't demean others in the entertainment business with actual ability.

Note that the mere fact that performers have no particular ability doesn't mean they can't make plenty of money doing whatever it is that they do. The one ability that performers generally have is marketability. And as countless examples have shown, the ability to be marketed (and to market one's self) is far more important than musical or acting talent anyway.
Recent examples of performers:

Britney Spears
Paris Hilton
Hilary Duff
All boy bands
Kevin Federline

A showcase of talent to an audience. The one thing that sums up all the hard work, time, and thought put into a work of beauty & art. It's a breathtaking and nerve-racking experience that only some have the chance to do.
