Why is the latest MacBook slow?

Question

macbook

Sorry, but I have a cry of the soul. I'll tell you in order. At home I have a second generation Core i3, 8Gb of RAM, a 64Gb SSD, no video card and Linux Mint 10. Everything flies. I have an iPhone 5 in my pocket and it practically flies too. I needed a laptop and I decided not to save money and take something that will certainly never slow down and the interface of which will be drawn perfectly smoothly.
Checked on models:
MacBook Air 2013 4Gb 13"
MacBook Pro 2013 4Gb 13"
MacBook Pro 2013 8Gb 13" (!)
Following steps:
1) Swipe up on the touchpad to switch to the view mode of all windows at once. This happens with strong jerks.
2) In safari, make the touchpad converge with your fingers in order to switch to the window rewind mode. This does not happen smoothly, but in a dozen and a half jerks.
3) Animation on some sites. Here is topodin.com expanding the "cases" tab and rewinding the page itself.
I definitely don’t understand why a laptop in 2014 bought for $1800 (8GB firmware in the CIS) can’t render me an animation of browsing windows in safari, while in 2009 on a computer for $300 I played with three-dimensional burning compiz-fusion cubes without a single hint of delay and with absolute smoothness. I do not understand how this can be allowed at all and how one can turn a blind eye to this.

Answer 1

MBA 2013 / i5 / 8Gb.
The swipe up is smooth.
In Safari, it really happens a little abruptly due to the specifics of the gesture: the progress of the action is tied to the movement of the fingers, the presence of a trigger threshold is noticeable, there is an automatic fine-tuning of the animation and its duration is not constant. Try to zoom slowly, if there is no smoothness, then there really is some kind of problem. OS X updated?

Answer 2

ME865, there are no such artifacts. Everything is smooth and fast. The old MacPro 4.1 had similar problems before the memory update, but I just increased the memory to 16 and everything was OK.

Answer 3

imac 2012 / i5 / 16Gb - everything is ok.
mbp 2013 (retina) / i5 / 8Gb - everything is ok.
mbp 2013 (retina) / i7 / 8Gb - everything is ok.
air 2010 / c2d / 2Gb - there are lags on both counts, but IMHO this laptop is obsolete)
Everywhere is 10.9.2
