Oct 20, 2014 12:23 PM in response to category38by Daz101,First time i am posting but thought i had to, i had the same problem with 2012 MBP with 8GB RAM. Boot up time so slow compared to Mavericks and Safari was slow and really annoying....I gave it two days to see if it improved - it did not. So my solution was time machine back to Mavericks and machine back up to speed. Hopefully Apple will sort it without having to replace hard drives...

Oct 20, 2014 2:17 PM in response to rshandsby rshands,Followup: ran a hard drive benchmark from https://itunes.apple.com/us/app/blackmagic-disk-speed-test/id425264550?mt=12
Running Mavericks my score would be 85-100MBps and now with Yosemite it's 50-65MBps. Has anyone else run similar tests? My guess is that in Yosemite Apple has changed sata settings. This would affect both HDDs and SSDs but probably not PCI-e flash storage on newer Macs.

Oct 20, 2014 7:47 PM in response to rshandsby shpankey,seems my networking is considerably slower too now. i'm hosting a Plex server, and now accessing videos remotely is insanely slow compared to what it was on Mavericks. I've went from 8mps videos smooth as butter (could even go higher) to 1mps and it still is choppy and cuts in and out.

Oct 21, 2014 5:17 AM in response to Todd Getzby snig27,I found that killing the transparency fixed a large part of my problems. Given the amount of noise on the web at the moment though, it seems this OS is kinda buggy.

Oct 21, 2014 10:16 AM in response to Todd Getzby flaghand,Following the steps that outlined on page 1 fixed the issues on my 2010 MacBook Pro (8 GB RAM) and on my late 2011 iMac.
I also own Clean My Mac 2 and running that regularly helps too.

Oct 21, 2014 6:30 PM in response to Todd Getzby lbald,I have the same issues with my Macbook Pro 2010 15 GT330M 8GB RAM 256SSD. After clean install of Yosemite, I had graphic glitches and the whole system was very slow and laggy. That's why I am back to Mavericks, but now I can't use iCloud bei Pages and Numbers (iWork). I am very disappointed with Apple! iOS8 and Yosemite not the best Product anymore.

Oct 21, 2014 8:56 PM in response to Todd Getzby asgowtham,Had the same problem, finally realized that the FileVault Encryption was struck at 19%. Speed back up to normal after I disabled FileVault using terminal command - sudo fdesetup diable
To check whether the FileVault is the culprit, go to System Preferences --> Security & Privacy --> FileVault to see if encryption is in progress.. For me the blue bar was less than a quarter with status 'estimating time remaining'..
Then open Terminal and type in: sudo fdesetup disable
It will then ask for the admin password (to be it asked twice), then it was disabled... Back to normal life again..
Here is my terminal log for reference:

Oct 22, 2014 1:16 AM in response to asgowthamby lbald,I don't think it's just FileVault problem, it's especially because of bad drivers for NVIDIA 330m. If I try to set the finder window to FULLSCREEN, I have big graphic glitches, the same thing with youtube video and fullscreen.

Oct 22, 2014 7:51 AM in response to kamalchaby lbald,reduce transparency - I tried it also, but it didn't help to me!!

Oct 22, 2014 8:42 AM in response to asgowthamby DearestClaudio,Just checked the FileVault thing out for myself and lo and behold it was frozen halfway through the setup. I'll test things out now that it's disabled and see if that fixed things for me. Thanks for bringing that up, @asgowtham, I had no idea it even existed!

Oct 22, 2014 9:12 AM in response to Todd Getzby CakemanPA,From a terminal session I did "
sudofdesetup disable" this turned off FileVault and started the decryption process. I am seeing some increased responsiveness. I can actually see letters as I type them. 5 hours of decryption to go. Apple never should have turned the default to FileVault to ON. -
Oct 22, 2014 9:28 AM in response to CakemanPAby DearestClaudio,Disabling FileVault immediately had a huge impact for me. Virtually all the issues that I was experiencing are solved. I don't know why they thought it was a good idea to make FileVault encryption opt-out rather than opt-in, but it's pretty safe to say that it was a pretty big mistake on their part.
