Hello,
I've no benchmark for used havp with ramfs, or without! I'm running my machines with ramfs and can say it's a little bit faster as with harddisk used.
Important thing to know is, that you have to enable a little bit more ram disk size at boot time, because per default the ramdisk size is 2MB, or 4MB dependendt to your used distribution.
The only thing, you have to do is, to add ramdisk_size=64000 in your grub settings like:
Code:
kernel /boot/vmlinuz-2.6.35.4 root=UUID=97992898-1862-4d8f-a980-0a1fbe03cde4 ro edd=off ramdisk_size=64000
This give you a ramdisk size about 64MB! Normally 16MB should be enough. My systems are using 8MB on maximum.
Regards
