# Install ```bash sudo npm install -g p3x-ramdisk --unsafe-perm=true --allow-root ```
## IntelliJ Speed Based on: http://sheroz.com/pages/blog/improving-development-performance-moving-intellij-idea-cache-ramdisk.html ```text After all these tricks I tried to open my current project with IntelliJ IDEA 12 … Wow!!! It is fantastic! Works like a … sword!!! Why sword?! I don’t know exactly. May be because of Darcula theme. This is just first thought what came to my mind seeing the overall results. The Intellij IDEA 12 now works as a lightsaber sword, as a weapon of a Jedi Knight, which you can trust in Java world! ```
* Requires tmpfs, bash, fstab, rsync, memory :) * Usually, all requirements of every Unix flavor are installed by default * SystemD * Service * Timer * Suspend * RAM disk to HDD * Linux, Unix, BSD, macOS * Should might need some tuning, but the functions are there, I just only tested in Linux.
## Intel Optane I think my ramdisk is faster. :) Ciao!!!
# Use case Speed up IntelliJ and development Node. (Tons of files.) The result is that the development is many folds faster. No waiting at all. # Install ```text patrikx3@workstation ~ $ p3x-ramdisk install --help Usage: install [options] <uid> Install a p3x-ramdisk Options: -h, --help output usage information -r, --rampath [path] The path of the ram disk, default /home/$USERNAME/ramdisk -p, --persistent [path] The path of the ram persistent, default /home/$USERNAME/ramdisk-persistent -g, --gid [group] The gid, it you omit it is the current user -t, --timer [minutes] The timer in minutes, minimum about 10 minutes, Default is 20 minutes, the best
-s, --size [megabytes] Ramdisk in size of megabytes, default is 4096 megabytes
``` # IMPORTANT Trash is disabled in GNOME with p3x-ramdisk. It will ask for confirm to delete data. You might have it in the previous save. It is possible to enable trash bin, but for me is not important now, so I disabled, memory is not cheap. # Setup **Use GitHub for info, NPM hides wide strings.** https://github.com/patrikx3/ramdisk ```bash # of course your data will never be deleted, # double persistence (current, previouse, saves every 20 minutes) # load on boot, plus at shutdown and suspend it saves sudo npm install -g p3x-ramdisk # install # if you need less/more memory, add -s 1024 or even more, 10GB is good :)
sudo p3x-ramdisk install $USERNAME
# Get the output, add to /etc/fstab

sudo mount -a # you should verify the ramdisk is existing now, you might have to reboot # on linux it can show your settings, like below: df -h # if there is an error, you can sudo p3x-ramdisk stop # if all good # STARTUP THE RAMDISK PERSISTENT sudo p3x-ramdisk start # you can work like here # /home/$USERNAME/ramdisk/persistence/content # SOME DEBUG p3x-ramdisk watch # to trigger a savs p3x-ramdisk save # you don't need usually to save # the default is 20 minutes # the systemd service saves on suspend and shutdown # to stop the services # removes sync, so the ramdisk files will be unavailable, # only be in /home/username/ramdisk-persistent/current sudo p3x-ramdisk stop # your duplicate copies are ls -all /home/$USERNAME/ramdisk-persistent/current/ ls -all /home/$USERNAME/ramdisk-persistent/previous/ # you are done # the default use case is to speed up working with IntelliJ and my projects to ramdisk # if you just want persistent folder and that's all # there is a special folder, .p3x-ramdisk-link # everything there is linked into /home/$USERNAME # if there is nothing in .p3x-ramdisk-link # no linking is. to test it, you might not need it. ```
