It doesn't matter if you can or cannot replace it with other words. It's what the industry has decided is an appropriate term to use in the circumstances. > in addition to being vague and essentially meaningless in most contexts It's not vague, it has a literal meaning. Efficient. The definition comes from the French word "performant", the meaning of which goes back to the 17th century. This isn't people going "ohh it's related to performance, let's make up a word that sounds similar", like "supposably" or similar. It's "Let's take an established word with the same roots that has the same meaning as we want and use it".

> It's not vague, it has a literal meaning. Efficient. See a sister thread for commenters mock debating over whether it means improved throughput or reduced latency. If a speaker indeed intends to mean “efficient,” then it would be thoughtful to opt to instead use “efficient” for clarity’s sake. Performant has been so often recklessly used that the meaning has been diluted to mean general and vague “fastness,” from which most thoughtful people cannot glean any specific meaning.
