Functioning well or as expected.

[Merna]

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 dont need to worry about it and can look for optimisations elsewhere in your system.

[Lanell]

Something that has [adequate] or better [performance]. Combination of [Performance] and Conformant. Commonly used by Microsofties but not a real word.
