Drive to transfer virtual memory using MAC OS x

The design of virtual memory for MAC OS X lets us no longer use an application software to half the time to see a memory-less dialog box, and then have to turn off its application and set it up with a little more memory.

Virtual memory is to use the space of the hard disk as memory, according to DDIF this website said, if you have two hard drives, and the virtual memory used by the hard drive to the second hard drive, the overall efficiency of the system to improve.

Set the file location of the virtual memory interchange file in/ETC/RC, which will be set at the beginning of the Power-on program (start up sequence), with a row near the end of the file

swapdir = /private/var/vm

is to try to set the virtual memory and where to do the exchange of files.

The problem is, at the early stage of the boot process, the system has not seen the second hard drive, so we can't just change the path directly to the second hard drive in this place. So you need to put the following program code, early Mount the rest of the hard drive and so on.

##

You have to put this piece of code in the

Swapdir =/PRIAVTE/VAR/VM

Before that, the second disk can be Mount early and allow us to place the path of the virtual memory to swap the file on the second disk.

The path to the swap file must be changed after the disk is Mount out

Will

swapdir=/private/var/vm

Change into

swapdir=/Volumes/second_hard_drive/private/var/vm

Second_hard_drive is the name of your second hard drive.

In this way, after the reboot, the whole system should be running faster, especially when you are using multiple software.
