OS X Yosemite will be faster?

Question

macOS

Will she work faster? Interface display speed is of interest.

Answer 1

Installed on MC270. Works much faster than snowball (10.6.8). But the first beta was very raw. On the forms, the elements were located somehow and sometimes vydzhal outside the framework of the form itself.

Answer 2

I've been on Yosemite Beta for two weeks.
WindowServer heats the processor well. The system is slower than 10.9, especially if you do not log out or reboot for a long time. Perhaps the release will be faster, but I do not think that much.
PS On my MBP mid 2010 performance rating in descending order: 10.6, 10.8, 10.9, 10.10, 10.7.
