Mount a temporary ram partition

mount -t tmpfs tmpfs /mnt -o size=1024m
Makes a partition in ram which is useful if you need a temporary working space as read/write access is fast. Be aware that anything saved in this partition will be gone after your computer is turned off.

What Others Think

many systems come with a shared-memory "Device" pre-mounted. My distro (fedora) is mounted at /dev/shm. Pretty handy when you want to borrow some ram for disk like purposes.

this is really great if you run gentoo and are going to compile something - if you mount a tmpfs at /var/tmp/portage, it'll emerge while storing temp files in ram instead of on the harddrive, leading to a faster emerge that doesn't bog down your harddrive. Take note though, not everything will compile if you don't have enough ram, esp. if it's something like gcc or gtk... about 700mb should be fine (i think) this might be of interest too: https://wiki.ubuntu.com/BootToRAM

No doubt this would torn out the ram while doing heavy-duty work provided if mounted under restricted places ;)

I have a detailed (verbose) notes on tmpfs here: http://www.askapache.com/web-hosting/super-speed-secrets.html

the truth is... hard disks suck. they're cheap, yes, but they're slow. and they fail. if you have lots of redundancy, then maybe you can overcome these deficiencies through scale. but what about the end user masses who don't use some elaborate redundancy setup? i've been using mfs and tmpfs instead hard disk for quite some time for both "code" and "data". i only use hard disk for stuff i need to save. after using ram exclusively for a while you begin to see just how slow and unreliable hard disks really are, and you'll unlikely want to go back to using disks. ram is the next best thing to the cpu's registers. there are quite few registers with the new cpus... it seems like overkill... b/c most of them are going unused. but they are there for speed. ram is ridiculously slow by comparison.

For OSX (tested on 10.7.3): diskutil eraseVolume HFS+ RAMDisk `hdid -nomount ram://$((1024*2048))` This will be mounted at /Volumes/RAMDisk/

On FreeBSD systems you can use : mdmfs -s 32m md /mnt

I use this with mysql for the tmp folder. any file sorts are done in ram rather than on disk. mount tmpfs /tmp/mysqltmp/ -t tmpfs -o size=15G
