100% performance improvement? That seems a little ridiculous (and impossible). I can't find the data that this claim comes from, so I have a feeling they might mean 50% performance improvement (i.e. 1s => 0.5s). Is there more detail anywhere?
(Edit: would it be possible to have an explanation for why this was downvoted? If I've said something stupid/wrong, I'd like to be corrected please.)
- mtgx 14y ago100% performance improvement = 2x as fast as before
- dbaupp 14y agoThanks! I just had the terminology backwards: performance is number of ops in a given time, not the amount of time for some number of ops. (It seems every time performance comes up I manage to get it wrong.)
- koide 14y agoTo begin with, it's perfectly possible to increase several orders of magnitude the performance of a piece of code, you can Google for plenty of examples. In addition, going from 1 sec to 0.5 sec is indeed 100% improvement. Given 0.5 sec = 1 ; 1 sec = x, then x = 2
- ars 14y agoGoing from 1s to 0.5s is not a 100% improvement, it's a 50% decrease (in time). i.e.: 100% increase = 50% decrease. Percents are weird to calculate.
- dbaupp 14y agoI know that going from 1 to 0.5 is a 50% decrease rather than a 100% improvement. (I actually said this in the parent comment.) But it's alright, I've got my definitions sorted out now.
