For example, 1024, 1024k, 1024m, 2G; or for example 50%, 75%, to use this percentage of your total RAM for the tmpfs partition.</p> The size variable could be anything that tmpfs accepts.

If you have a desktop machine with a SATA disk, the startup time could decrease for example from 3 seconds to 2 or so; it is much more noticeable on slower notebook disks. On my machine it made a huge difference.</p> <p>Regarding firefox, its another issue is that it loads a LOT of data from your profile on startup. So if you have lots of cache or haven't cleared your private data recently, it slows down the startup by several orders of magnitude. Just to exemplify, on my machine a 6-months-old profile took almost 30 seconds to startup. After cleaning the visited sites, downloads, cache, and so on, it dropped back to about 5 seconds.</p> For firefox, the speed improvements depend a lot on your hardware configuration.

i replaced “sudo” by “su -root” then my root password is allowed

toram and umount works well

i launch firefox then i don’t noticed any improvement

i use toram /usr/lib/firefox-3.6 35M

is it the good syntax ?

yes firefox is in /usr/lib/firefox-3.6/

perhaps all my ram is in use then the ram disk is in the swap ?

ksysguard points that my ram size is 2 GB and 600kB swap is in use before using toram and FF then i assume /usr/lib/firefox-3.6/ ram disk is in the swap isn’t it.

what would be a script to launch firefox and to automaticaly mount to ramdisk and when closing FF then dismount ram ?

and if i want 2 apps with directory in ramdisk, does it work ?
