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! ``` ## Features * Requires tmpfs, bash, fstab, rsync, memory :) * Usually, all requirements are available in many Unix flavors * SystemD * Service * Timer * Suspend * RAM disk to HDD * Linux for sure, easy to extend for 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. # Changelog * [Since **v2019.2.1**, BREAKING CHANGELOG](artifacts/readme/ # Install ## Warning Do not use the ```$USER``` variable, use the actual username, like ```p3x-robot```. ## So actual 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/{{USER}}/ramdisk -p, --persistent [path] The path of the ram persistent, default /home/{{USER}}/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.** ```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 --unsafe-perm=true --allow-root # install # if you need less/more memory, add -s 1024 or even more, 10GB is good :) sudo p3x-ramdisk install {{USER}} # Get the output, add to /etc/fstab echo "tmpfs /home/{{USER}}/ramdisk tmpfs gid=10000,uid=10000,size=4096M 0 0" | sudo tee -a /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 {{USER}} # if all good # STARTUP THE RAMDISK PERSISTENT sudo p3x-ramdisk start {{USER}} # you can work like here (this a symlink, so you can't accidentally delete # so next time boot, it will re-create the symlink ...) # /home/{{USER}}/ramdisk/p3x-persistence # SOME DEBUG p3x-ramdisk watch {{USER}} # to trigger a savs p3x-ramdisk save {{USER}} # 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 {{USER}} # your duplicate copies are ls -all /home/{{USER}}/ramdisk-persistent/current/ ls -all /home/{{USER}}/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/{{USER}} # if there is nothing in .p3x-ramdisk-link # no linking is. to test it, you might not need it. ``` ## Linkin' in /home ```bash ### //LINKING:START # LINKING -
