Fusion Drive is an OS X specific way of caching data. If you use Bootcamp on a Fusion Drive you will get Windows on the hard drive only. Some information from this Apple note
Hi, try this: Disable the "Display have separate Spaces" LogOff and Login again, check the process... all fine?
I had a similar issue with high cpu usage in WindowServer which I managed to get back to something more normal by removing any items in my menu bar that were making high frequency drawing updates. In my case it was the Network Monitor from Little Snitch that seemed to be the biggest culprit.
There is a workaround posted on the Apple forums. Pros: The mouse/key entry performance does "feel" significantly better, as does the momentum zoom. Zoom is per-screen, rather than both at once Cons: It is still not nearly as performant as it was in Mavericks. The testufo.com site will still not render at 60fps while zooming. While this workaround ...
FWIW, my experience is identical in all scenarios you describe (The original and both work-arounds). I'm using 10.10.1 on a 2014 Mini CoreI7 with 16GB of RAM and an SSD with two external 24" displays. I do see a very slight lag on the kraken.io site, but nothing awful. Some ideas on further troubleshooting steps — Each of these steps aim to reduce the ...
As you know with SATA connection you get 3 to 6 Gb/s. With Firewire you get < 1 Gb/s data transfer. To be specific: Firewire 800 is 800 Mbits/s (Mb/s) not 800 Mbytes/s (MB/s) [8 bits in a byte] its a common misconception. so Firewire 800 is rated up to 80 MB/s.
Best workaround so far: In System Preferences-Accessibility, select Increase contrast (which will implicitly select Reduce transparency). This seems to improve performance in some circumstances, but it does dramatically affects aesthetics. The slider on http://kraken.io is smooth while zoomed in. There are still some circumstances where zooming is a little ...
I just posted about what I did to solve the WindowServer message overload on my Yosemite version (10.10.1, which hadn't fixed it). From various comments that I'd found while googling the issue it seemed to me that the zero length preference files for WindowServer might be causing the problem (just a guess and as yet not confirmed by others since I just ...
Simplified explanation: When an application is started, an entry is written to disk that says this app is currently active. When an application quits, that entry is removed. When the system starts and finds entries in this list, it's an indicator that the system crashed or did not shut down properly and it can offer to relaunch those apps for you. It takes ...
From what I've collected yet, the following might be able to help you (find my personal experiences in italic): Mission Control: switch "Displays have separate Spaces off", switch Dashboard off. Dashboard as an overlay really slowed things down for me Fix disk permissions, reset System Management Controller, reset PRAM (Luis Mercado explained this well at ...
