Use with caution, consequences unknown. 

Open up Terminal on your Mac and type this:

nvram boot-args

You'll get an error message. Now copy and paste this line into terminal:

sudo nvram boot-args="serverperfmode=1 $(nvram boot-args 2>/dev/null | cut -f 2-)"

When you hit return, it will ask that you enter your admin password. You will not see anything when you type. Enter your password and hit return.

Now, once again, type:

nvram boot-args

You will see this:

boot-args. serverperfmode=1

Reboot your computer.
