/dev/sda1 / ext4 defaults,noatime,nodiratime,discard 0 0
Sorry for maybe silly question ... just want to be extra sure
Thanks for great link
Make these lines below any sense for me when I am not using swap at all?
1. Add the following to your /etc/rc.local file.
# Economize the SSD
sysctl -w vm.swappiness=1 # Strongly discourage swapping
sysctl -w vm.vfs_cache_pressure=50 # Don't shrink the inode cache aggressively
Is this very important for SSD disks? Can you point me somewhere to get more info about SSD and I/O Schedulers?
Change the I/O Scheduler
1. Edit the /etc/grub.conf file. Add “elevator=noop” to the kernel line.
kernel /vmlinuz-126.96.36.199-117.fc10.i686 ro root=/dev/sda
