Please don't compute speed-up like that.

Old time: 6 minutes (360 seconds). New time: 1 minute and 50 seconds (110 seconds). Speed-up calculated by article author: 1-110/360=0.694 (69.4% saved). Speed-up calculated by me: 360/110=3.27 (3 times faster).

Please calculate it the other way around. It makes great difference when you say you made something 10× faster than when you say you saved 90% of work even if both mean exactly the same thing.

Bruce Dawson has great article about this: https://randomascii.wordpress.com/2018/02/04/what-we-talk-ab...

I don't think this remark is warranted here. Your sentence ("3.27 times faster") is clear, but conveys the same meaning. His sentence ("loading times are cut down by 70%") does not refer to "speed" or "fast" (Ctrl+F the blog post to check for yourself) and is technically correct and clear. So the criticism raised in the WordPress article (about the usage of the words "speed" and "fast") does not apply. The mistake would have been to talk about "70% faster" or a "70% speed-up", because then there is ambiguity for the reader.

That's how you know he's a pure engineer - he used math not marketing

Agreed however that this is 3x faster.
