Will upgrading to Yosemite from Mavericks slow down my computer (even a little bit)?

    The best way to find out is to create a new partition, install Yosemite on the new partition, boot to the new partition and see how the system response is under Yosemite. When you are done, boot back to Mavericks partition and delete the new partition.

    Skip it. I upgraded and there is nothing new or better. Last 2 .x updates have been a step backwards. I would just stay on Mavericks.

    For a start, Finder itself is slower on Yosemite than in Mavericks even on SSD...
