mac os x /private temp virtual memory

Use RAM disk or HDD for temporary files

If you have enough RAM, you can dedicate (typically around 256 to 512 MB) of RAM to a RAM disk. RAM disk is a virtual disk that only resides in memory, so is suitable for storing data that need to live only until you shut down your computer. Temporary files are ideal for this. You can create a RAM disk during the boot time and redirect all the temporary files there. To do that, create a file named “MoveTempFoldersToRamDisk.sh” in your home directory and put the following content in:

#!/bin/bash

# +----------------------------------------------------------------------+

# |                                                                      |

# |  Set up Mac OS X to store temporary files in RAM rather than on disk.|

# |                                                                      |

Now, run the following in the Terminal:

chmod 755 ~/MoveTempFoldersToRamDisk.sh
~/MoveTempFoldersToRamDisk.sh

This creates two RAM disks on startup – one 256MB large for /private/tmp (command “RAMDisk /private/tmp 256″ in the middle of the above script) and another one 64MB large for /var/run. You can now delete ~/MoveTempFoldersToRamDisk.sh from your computer.
For the changes to take effect, you have to restart.

If you decide to undo this tweak in the future, you can do it simply by deleting /System/Library/StartupItems/RamFS directory from your Mac. E.g. by executing the following command in the Terminal:

sudo rm -rf /System/Library/StartupItems/RamFS

Again, restart is needed for this to take effect.

There are some small drawbacks to applying this tweak:

After applying it it takes a few seconds (2-3 on my machine) to shut down
It lowers the size of RAM usable for applications

If you are bothered by the above and have HDD in your Mac as well, you can consider moving the temporary files to HDD instead of the RAM disk. The steps are similar to moving the user home directories. E.g. to move /private/tmp, execute the following in the Terminal:

sudo ditto /private/tmp /Volumes/your_hdd_name/private/tmp
sudo rm -rf /private/tmp
sudo ln -s /Volumes/your_hdd_name/private/tmp /private/tmp

DISM clean WinSxS

Use the /StartComponentCleanup parameter

Using the /StartComponentCleanup parameter of Dism.exe on a running version of Windows 8.1 gives you similar results to running the StartComponentCleanup task in Task Scheduler, except previous versions of updated components will be immediately deleted (without a 30 day grace period) and you will not have a 1-hour timeout limitation.

From an elevated command prompt, type the following:
Dism.exe /online /Cleanup-Image /StartComponentCleanup
