- chaboud 5y agoI completely agree. X times the rate of Y is unambiguous.
- samhw 5y agoI highly recommend this blog post, which makes the same point among many (great) others: https://sled.rs/perf.html https://sled.rs/perf.html > When we speak about comparative metrics, it is also important to avoid saying commonly misunderstood things like “workload A is 15% slower than workload B”. Instead of saying “faster” it is helpful to speak in terms of latency or throughput, because both may be used to describe “speed” but they are in direct opposition to each other. Speaking in terms of relative percentages is often misleading. What does A (90) is 10% lower than B (100) mean if we don’t know their actual values? Many people would think that B is 1.1 * A, but in this case, 1.1 * 90 = 99. It is generally better to describe comparative measurements in terms of ratios rather than relative percentages. > The phrase workload A is 20% slower than workload B can be more clearly stated as workload A was measured to have a throughput of 4:5 that of workload B. Even though many people will see that and immediately translate it to “80%” in their heads, the chances of improperly reasoning about the difference are lower.
- alanfranz 5y agoI would say 2 times faster or 3 times the speed of the mac mini. Faster implies a delta already; I can say X is 0.5x faster than Y and it means its speed is 1.5x that if Y.
- hackerfromthefu 5y agoIn common usage I believe 3 times faster is what most people understand for these figures.
- dotancohen 5y agoIn common usage people refer to their mass as weight. Nobody says "I mass 75 kilos". I'm divided if that's an argument in favor or against your point, though.
- stackbutterflow 5y agoIs there a language where people don't use weight for mass?

- alanfranz 5y agoCommon usage doesn’t mean it’s correct or clear. Yes, a lot of people say 2 times faster but it isn’t. The whole point of this comment thread is just that.
- lostmsu 5y agoYou are definitely wrong. 1 times faster is not even a thing.
- alanfranz 5y agoVery bold statement without a reference. I’d say 1 time faster, but I usually say it’s 2x the speed to prevent confusion.
