I elected to move only relatively static files onto the Ramdisk, so once I have one good reboot, I should always find my Ramdisk in the state I need it. The Ramdisk I selected has an option to persist state upon system shutdown (assuming there is no crash).

Use the mklink /J command to make a link from the place on disk where the directory used to be before you renamed it to where you copied it on the Ramdisk.

Rename the original folder (I added -COPY to the end).

There's a neat trick that lets you move folders (or files for that matter) to the virtual disk without making a single change to configuration.

JDK (deleted some unnecessary files e.g.

Is there a free/open source tool for Vista that will show me which files are used most frequently during a period of time to reduce the guesswork? What other files/directories might be candidates to place on the Ramdisk? Eclipse-related files? (Parts of) the JDK?

There are roughly 500MB still free on the Ramdisk when the work directory is fully utilized, so room for plenty more. That significantly improves server startup times but does nothing for compile times. Using the Vista mklink command, I created a hard link from where the SpringSource dm Server's work area normally resides to the Ramdisk. However, the 3.3GB available to the OS is often sufficient and there are many situations where we do not use the swap file(s) much.Īnother option is to use the Ramdisk as a location for temporary files. That works, and noticeably speeds up development in low memory situations. One option is to configure Vista to swap to the Ramdisk. The slowest part of development for us is compiling as well as launching SpringSource dm Server. I came across several Ramdisk drivers that can create a virtual disk from the OS-hidden RAM and am looking for suggestions how best to use the 740MB virtual disk to speed development in our environment. The OS exposes roughly 3.3GB of RAM due to reservations for hardware etc.

We're developing Java/SpringSource applications with Eclipse on 32-bit Vista machines with 4GB RAM.
