I know, I'm just using compression as an argument to show how significant 30%+ is.


sort by: page size:

Wow, I wouldn't have expected that. Do you have a reference for the 30%? I'd like to see what is going on to cause that big of a difference.

Oh, you are right. It looks like it's around 9.5% according to a quick simulation I ran.

We can agree to disagree, but I don't consider 30% to be close. Maybe for applications that aren't time-sensitive, but I rarely deal with those.

Good point but you should probably use the prob that it's 75% or higher.

In nearly every subfield of computing, along nearly every metric, most people would kill for a 20% improvement.

A processor 20% faster would dominate the market for years. A new compression algorithm that was 20% smaller would be either copied or used by every archiving system. And yes, a website reduced by 20% is significant.


30/186 == ~0.16.

16% is very different from 30%. Still important, but just a little over half as much.


30% kinda provokes sticker shock.

What if you went with max (5%, 0.01/MB)? 30% of 0 is still 0, after all.


those statements sound like incredible cherrypicking

does 1.11% sound a lot an is it statistically significant?

cut page in half from what to what? from 30 to 15 seconds? or from 2 to 1?

improving one second like how? from 12 to 11 or from 2 to 1? and is 2% really substantial?


The difference between 0.5% and 30-40% is 2 orders of magnitude.

This kind of arithmetic is always very unclear and causes all kinds of confusion / miscommunication. This is why I always prefer to be explicit about the absolute numbers (maybe in addition to the relative percentages): "it used 100 mb and now it uses 25 mb (which is a 300% reduction when looking at the final result / which is a 75% reduction based on the initial result)".

Are you sure it isn't 76% with all that hard cold data you're using?

It won't be 30% less. It'll be 10% less.

Is this the lingo that statisticians/mathematicians use?

I’d just say 75% drop for 100mb to 25mb.


Definitely not 20-30%. Maybe 10% on certain workloads.

No, it's about 0.25% of it by number of cables released, to be precise.

the performance hit is 20% typically. it is significant.

Just to be clear:

60/300= 20%

80/300= 26%

Not much of a difference, IMO. Make your case if you disagree.


That is actually 55% more (or three other way around, 35% less)

It's actually 42.9% more. 1 / (1 - 0.3) = about 1.429.
