Instead of writing your tmp files to /tmp, now write them to /var/tmp. This should give you a small space for your garbage. If you dont have it, see the miniroot HOWTO for mounting via loopback. Which should report (among the other disks) a tmpfs with 1024 1K blocks (=1MB) as /var/tmpįilesystem 1K-blocks Used Available Use% Mounted on Make sure ram disk support is compiled in your kernel. It helps to create a virtual disk where the temporary files and cache files can be stored, so that web applications and large files can be loaded a lot faster. To check if your operation succeeded issue Tmpfs /var/tmp tmpfs nodev,nosuid,size=1M 0 0 Goal is to have a 1MB directory in RAM for temporarily storage. This guide shows how to set up a 1 MB RAM drive on your Raspberry Pi.įor more elaborate instructions, see Moving Log and Temporary Files To a RAM Drive Setup To avoid SD card wearing these files could be written to a virtual drive in RAM. But the only way to exchange data between Lua and shell scripts is through temporarily files. If you have enough RAM to make ram disk useful, swap file will not be used anyway but if you dont have some ridiculous amount of RAM and stile make a ram disk, it might have to swap to disk anyway. 4 seconds, Photoshop with a giant TIF in just 4.8 seconds and Excel with a huge spreadsheet in just 1.9 seconds.It is strongly believed that excessive writing to the Raspberry Pi's SD card will finally cause it to fail. One of good reasons for ram disk would be to use for scratch/temp files in programs like Adobe for instance. With the two together, we were able to load Word 2010 in a mere. If you can possibly afford it, the combination of SSD with RAM Disk is simply unbeatable. Considering that buying additional RAM is a lot cheaper than upgrading to SSD, many users may find the RAM Disk a cheaper option. However, the SSD alone was noticeably faster than the HDD RAM Disk combo in some cases, particularly when loading the heavy Photoshop CS 5.1 application. However, on a typical PC the Users and Common folders are so huge that you'd need a lot more than 4GB of available RAM Disk space to house them.Īs you can see in the chart, using the RAM Disk with the hard drive cut load times in half. Create a ramdisk device if one does not already exist in /dev: /home/tony mknod -m 660 /dev/ram b 1 1 /home/tony chown root. If you use applications that don't write to any folder but C:\Program Files or if you're able to move the entirety of your C:\Program Files\Common Files folder and your C:\Users folder over to the RAM Disk, you'll achieve maximum performance with any storage drive as everything will load from RAM. Making a generic ram disk Make sure ram disk support is compiled in your kernel. Because part of the software, at least in our tests, remained on the storage drive, pairing the RAMDisk with an SSD proved the fastest option. However, even with the hard drive, the difference in launch times with the RAM disk was dramatic. To see the difference, we loaded four popular applications - Adobe Reader, Excel 2010, Photoshop CS 5.1 and Word 2010 - onto the hard drive, timed their open times and then installed them on the RAM Disk instead. We then applied the same tests, using a speedy Kingston HyperX SH100S3 SSD instead of a hard drive in the same notebook.īecause most applications leave at least some of their files in a variety of folders on the C drive by default (ex: C:\Program Files\Common Files) none of these applications loaded completely from memory, even after we installed them to the RAM Disk. In real life, these speedy transfer speeds result in much faster application opens.
