Speed up Chrome with a ram disk

If you have at least 4gb of ram and you don’t use memory needy applications, this can speed up Chrome.

If you can sacrifice at least 1gb of installed ram to use with a ram disk, you can have Chrome use the ram disk to store its cache.

Direct Chrome’s cache to your new drive

  1. Close Chrome if it is open
  2. Right Click on your Chrome shortcut, go to properties and add the following behind the Chrome.exe extension:
    –disk-cache-dir=E:           Substitute the drive letter with the ram drive you made
  3. Click on Apply and then OK
  4. Open Chrome and surf the web
  5. Go to Computer and make sure cache is being added to your RAM disk


Remember that ram disks are volatile.  Once you reboot your computer, the Chrome cache will automatically clear out.   This will keep your computer clean however if you save passwords on the web, you will have to re-enter the passwords.

Benchmarking should show a 20%-40% gain in load times.  Remember, cache is used when a page or item is loaded after the first time.
