SuperFetch

SuperFetch is a feature of Windows which caches executable code in spare memory so it is available when needed. Windows also uses available RAM for other types of disk cacheing. However it makes a best guess on what to cache, and is tuned towards average end users.

Developers

Developers can benefit from moving the following types of files to a RamDisk:

Copies of databases for use during development and testing.
Source Code - This speeds up compilation. Data loss? Get a UPS, and checkin frequently. Good practices anwyays.
Compilation output - EXE, DLL, PDB, etc.
Temporary files used by your application, and development environment.
I have moved several of my larger projects to use a RAM drive. I formerly had 4 GB of RAM and dedicated 1 GB to a RAM disk. 1 GB holds a lot of source code and output. You can also use backing images and change the RanDisk contents depending on the project you are working on at that moment. I've now upgraded to 8 GB, but still only dedicate 1 GB of RAM to my RamDisk, and find it is more than sufficient for my needs, even on large projects such as Cosmos. Cosmos even with outputs, ISOs, etc uses only 256 MB.

Since moving to a RamDisk, my builds have reduced in time by 10-20x in many cases.

Startup Batch File

imdisk -d -m M:
imdisk -a -s 1G -m M: -p "/fs:NTFS /V:MemDisk /q /y"

mkdir m:\Temp

xcopy D:\MemDisk\*.* m:\*.* /E /K /H /R /Q
imdisk must be run as Administrator, so run the batch file as administrator. Batch files cannot be set to auto run as admin, but you can automate this by creating a shortcut to the batch file, and using the advanced button on the shortcut tab of the shortcut properties. Do not try to use the compatibility tab, run as admin will be disabled there.

Shutdown Batch File

del m:\temp\*.* /S /Q /F
rmdir m:\temp

REM Have to copy all, not just archived, else deleted files will reappear on boot
del D:\MemDisk\*.* /S /Q /F

xcopy m:\*.* D:\MemDisk\*.* /E /K /H /R /Q

imdisk -d -m M:
