Running somewhat sluggish for me as well, as well as 100% CPU usage on one core (iMac 2011).
Originally when I installed Yosemite I did not have this issue, over night is was fine, and during the day today it developed this issue.
Nothing changed/added during that time.
Hopefully they get this addressed quickly.
Not sure if related or not, but this is only ting I see in console related to Fusion:

I believe FileVault is is turned on by default. Can you verify ?
it is not on now, nor has it ever. I was given the option to turn it on during the upgrade process. I declined.
Nope, my filevalt is/was off.
Also I noticed if I keep constantly move the mouse directly in the VM itself the speed comes back. However as soon I stop moving the mouse, the VM slows down to a crawl.
I have the same issue with Mid 2011 iMac. 1 3.1GHz core at 100%. Hope this gets fixed soon.
I'm seeing the same thing. Was working fine, then today, very slow. Both my Win 8.1 VM and my Mac OS X 10.7 VM. Tried making a new Win 8.1 VM, install is going very slowly. Looked in console log for Fusion, see this line repeated about once per second:
2014-10-19T11:26:52.650-06:00| VMware Fusion| I120: VMHSGetDataFileKey: Could not get the dataFileKey from VMDB

Just an endless scroll.
Throwing myself into this. Same issue. Mavericks was fine with Fusion 7. Fusion 7 with Yosemite is slow to the point of being almost useless.
Same story here. My Windows 7 Guest is already running flawless since 2012. Upgraded to Yosemite. Was running Fusion 6. My Guest slowed down such that it is almost unusable.
Upgraded to Fusion 7. Same story. Removed old snapshots and cleaned up and reclaimed space.
Same story boot is endless. System is slow as hell. Completely unacceptable.
I have the same issue. Upgraded mavericks to Yosemite and vm performance is terrible for windows 8 VM's on both Fusion 6 and 7. Strangely though windows NT4 seems to work fine :-).
I have the same side effect where if the mouse is moved within the window the VM speeds up, sounds like some kind of Interrupt issue to me.
I never had this issue on Yosemite beta when booting from another drive with Fusion 7.
Well, it seems that the update to Yosemite is tickling a rather nasty performance problem somewhere. I haven't heard any reports yet of this problem being encountered by anyone here at VMware, so I'll need some help from those of you who are encountering this problem to help us to understand it...
First step: Launch Activity Monitor , choose View > All Processes, and see if it shows which process is consuming the CPU. Is it VMware Fusion, vmware-vmx, some other process, or does no process show up as using the CPU?
Please select the vmware-vmx process in the list and choose View > Sample Process. Enter your password if prompted. When the sampling is complete, choose the Save... button in the upper-right corner, save it to a file, then attach that file to a post back here.
Any idea roughly how long the sampling process should take? Been running for 15 minutes so far....
