Performant is not a word. Use a word more specific to your meaning, perhaps "efficient" in this context.

Well, what once was not, certainly now appears to be. It's been used so much, I think it's fair to say it has become a word. Moans and koans to contrary will be accepted, however. And hey, if you're lucky its existence will be short-lived.

"Performant" is a perfectly fine word. You might even call it cromulent.

I found my self thinking that performant is definitely a word, and it is, in French.

  Those example words have precise meaning, "performant" does not. Engineers should communicate using precise language, like other technical disciplines.

    I think that's what bugs me about "performant" --- it feels like vague buzzwordy management-speak, because there's already a well-understood word for the same concept: "fast". Ditto for "lightweight"; "small" gets the point across clearly, and if it's both fast and small, it's "efficient". Software can be big or small, fast or slow, efficient or inefficient (for combinations of size and speed.) I don't think we need any more adjectives beyond those. Instead of "significantly less performant", you could just say "much slower". (Note that LOOP was much slower on older Intel CPUs, but was the same as the longer sequence on AMD's. It would not surprise me if newer Intel ones now decode LOOP into the same sequence of uops. In any case, unless the loop is a tiny one, what happens in the body is likely to make a much more significant difference, especially if cache misses are involved.) Some interesting reading on why LOOP was slower on Intel CPUs --- because Windows 95's timing loop used it (observe the lack of "performant" in any of those posts): https://groups.google.com/d/topic/alt.windows98/liuMAIctHRg https://groups.google.com/d/topic/alt.windows98/liuMAIctHRg

      But do you think it's not a word? Also, I think performant is often used as a synonym for "fast enough", which is slightly different than "fast."
  - dalke 10y ago
    What's imprecise about: "Performant: 1) meeting the objective, often applied to a performance objective, 2) productive"? In looking around just now, economics seems to prefer the second definition, which is why I added it. All of the uses I found are compatible with this definition. What's the definition of "object oriented" again?

I basically cringe and stop taking an author seriously when they use the non-word "performant", but I've kind of given up pointing it out. Brother, we're losing the fight to people who think it's perfectly cromulent to embetter the language by innoventing their own words.

  What defines a language anyways? Languages evolve. That's the beauty of them: They aren't set in stone. Who knows? Maybe in a few decades, "your" will actually have a definition added for "you are" instead of the (currently correct) "you're". "Computer" used to refer to an actual person. "Caught" and "cot" used to be pronounced differently; now they are slowly merging.[0] Languages evolve. Whether for better or worse is up to the reader. If it weren't for evolving languages, we'd all still be writing like Shakespeare.

It is a word. Performant means "performing well". I wonder if can we apply this kind of adjective-forming to other verbs, e.g. by taking the gerund form, removing "-ing" and adding the suffix "-ant". For example: - observing => observant =?= observing well (yes, exists in this meaning) - informing => informant =?= informing well (does not exist as adjective, but could in the future?) - thinking => thinkant =?= thinking well (does not exist at all, but could in the future?)
- saynsedit 10y ago
  "Performs well" has no concrete meaning. It almost always requires a second question for clarification, e.g. "What does good performance specifically mean here?" Or "performs well compared to what?" Scientist, doctors, lawyers, and other engineering disciplines use precise words. Software engineers should too. As more and more people use "performant" fewer and fewer people will understand what good performance actually means. I wouldn't be surprised if this encourages a culture of wasteful premature optimization.
