more proof of how badly optimized Yosemite is...

Another Chinese saying, "It does not matter if the cat is black or white, only if it can catch mice." Or even a better one concerning the bad mouthing of forum posting. "Old Chinese Proverb say's "Do not remove a fly from the foreheads of others with a hatchet.

Words have power, and using them in a soft manor brings friendship to our forum.

I ABSOLUTELY agree with this. And, yes, as long as we reach the goal, everything happened, good or bad, would mean nothing, after that.

Whether words, axes, iPhone, they are all tools. Use tools well, and they could serve us well. Otherwise, see what unexpected would happen.

Kinda shows its not badly-optimised code (that would still have an issue), but installation-related variables at play.

Can you explain?

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.

OS X manages memory differently to how you think as far as I can tell, on a 4GB machine it will be using all of it apparantly continuously quite easily but you should be guided by the activity monitor, the memory pressure graph is a good general indicator of ram pressure but bear in mind you can almost always open more apps than the system can cope with, the graph will show you were that point is, do not be mislead by your interpretation of a single free memory number using windows definitions.

As I said in the post following the one quoted, I dont have any further details on what those variables might be but something has to account for the variety of experiences users have. Bad code is bad code, Yosemite would be incapable of running properly under any circumstances, clearly that isnt the case therefore other variables are at work, some may be installation environment (hw, sw), others maybe install method (clean vs upgrade), and there may be interactions of the two.

I read the article but not every thread here.

It seems he's comparing UI elements more than anything else. They can give the appearance of a slow OS.

Windows has always had a smooth UI and better drivers for 2D and 3D. Games always run better than their OSX counterparts.

Apple really needs to get on the ball with their drivers or allow 3rd party GPU driver installations. Maybe it's just their scaling algorithm that's poor. My non-retina MBP doesn't seem to have any UI lag.

I'd like to see the CPU and SSD benchmarked with Geekbench on both OS's on the rMB. Maybe a large file copy over Wifi to test network throughput as well?

There is some truth in your assumption.I planned another clean install in sunday but i didn't power my mac i decided spent some time with my new born daughter .So I did it yesterday - third clean install accompanied with two smc and prram resets .This time i haven't experience the bluetooth problemalso now use a monochrome background with reduce transparency.Things are a little snappier all around,that a pity because yosemite is a real beauty combine with a retina screen.Problem that remain and hurt my sanity- after some hours of usage general slugginess begins to show and stay even if i quit the apps with temporarily solution a restart.With my previous mac same workflow same apps(older versions)less ram,cpu and gpu recourses i restarted only for secondary updates...

Good call - and congratulations!
