Do somebody want to try a tweak found on ubuntu forum?
It seems that read a compressed squash file is faster than read the same file on HDD, so the tweak proposed is to mount /USR compressed and make it readable.
Caution, the /USR is then only readable, to make it RW another tweak is required, on the same forum they also describe operation.
I ll try to translate the procedure in english
copy your current /usr on another place (in case there is a pb...)
mksquashfs . /usr.sq -info
This operation can take time, be patient
Your usr.sq is ready, remove your current /usr and then modify fstab to create mounting point for usr.sq in new /usr empty
sudo mkdir /usr
remove your current /usr and then modify fstab
add following lines:
/usr.sq /usr squashfs loop,ro,nodev 0 0
It seems that network manager can have problems, only solution seems to use wicd.....
According to author, you can notice a gain of speed concerning applications opening etc...
But be careful to decompress usr.sq before any upgrade!
a more hardcore solution is to put the usr.sq in ram (if your ram is bigger than the file... and then everything flies!!!)
Do anybody want to try?
