Kinda shows its not badly-optimised code (that would still have an issue), but installation-related variables at play.
I even have transparency on, still smooth.
Why is it like this? Why can't it have worked like this before?
Just did a fresh install last night, and now it's smooth.
After you reinstalled all your third party applications the UI is still smooth?
So out of curiosity, what was the system performance like when you first got your MacBook Pro?
I keep reading people with the same hardware (even on retina) having opposing experiences with the UI where one would post their having extreme lag and another posts not seeing any lag.
On 16 GB? That's just silly.
OS X will tend to store more in RAM if a lot of the RAM is free, but it will limit that as it becomes close to being full. That's why my 2 GB MacBook Air can last a while on 2 GB while your Mac with 16 GB goes past 2 GB used immediately on a clean login.
As simonsi mentioned, as long as Memory Pressure in Activity Monitor is green, even if the RAM appears to be full, it's not a problem.
Are you looking at free memory or wired/active/inactive/used?It has never been my experience that Mac OS is good with memory management. Memory is rarely freed and I find I need to reboot after a while. I have 16GB on a Retina Pro 15.
Reading this thread, it has become clear that I had better make sure I only post about how great Yosemite is, and all posts need to be in pristine English. Talk about blinkered viewpoints.

Does not matter what Activity Monitor says...
Its a systemic issue.
I can't imagine how bad it is on devices without SSD's and lower memory configurations.
There was no need for that.
We are not talk here about broken yosemite installations and first time mac users.This is about yosemite bad coding in newer macs and of course some of us ranting our workflow ****ed up.That's strange, because I got a different impression. The view from where I am sitting was that there was considerable ranting and stamping of feet.
Surely everyone must know by now that not everybodies installation of Yosemite is broken, just a vocal minority. I take away the lesson that YMMV.

To make a more general observation (not necessarily about Yosemite) as a member since 2008. When I first started searching this forum to help with my transition from using only PC's as I added a Mac it was a more friendly place.
Now days the place is infested with new blood looking to pounce on any and every statement which does not embody and conform to their ideals.
Yes, there are still a few old timers here who display good manners, avoid derogatory remarks, and are very helpful in giving solutions to forum members. However, the scales are tipping very fast toward radical bitching attacks between members. Might be better to invest the $25 donation to MacRumors next year on the new Apple OS Manual by O'Reilly and forgo all this forum bickering, arguing, personal attacking and focus on answers to computer issues.
This post is in no way directed to the sincere helpful people who day after day offer their knowledge and opinions to the forum members.
Windows define free memory as memory not used or contain no valuable data, and will be assigned to any new application which request memory.
I don't know how mac define free memory. Maybe they have completely different idea to manage memory. To understand This I may need to borrow a book discussing Unix operating system.
But according to my experience, Mac OS X Yosemite may have some weird memory management issues. I say may because my mac has only 4gb memory. And I can see many times cursor becomes a beach ball.
The thread has been cleaned up. The post it was referencing has been removed presumably by the mods. I'm not the one unaware of the forum rules.
It's still there, as of now.
How do you know the beachball is caused by the RAM, and not for example a slow HDD?

I have heard a really good Chinese slogan. It says nowadays, bad guys are driving away good guys. ( Chinese version contains more meaning) I think this should be the real side of human: chase after the dark side, become powerful, and crush others who dare oppose him.
