1. Edit /etc/fstab, add mount options to /dev/sda4 (Data partition) and /dev/md0 (root):
	noatime,nodiratime,commit=60

2. Ramlog already installed in all firmwares. But you can install it manually (Or update preinstalled):
cd /tmp
wget http://www.tremende.com/ramlog/download/ramlog_2.0.0_all.deb
dpkg -i ramlog_2.0.0_all.deb
rm ramlog_2.0.0_all.deb

3. Disable some services:
update-rc.d bootlogd disable
update-rc.d rrdcached disable
update-rc.d collectd disable
update-rc.d monit disable
# Also you can change start option in /etc/default/*service_name*
insserv -v -d

4. Disable unusual cron jobs:
crontab -e
# Move fake-hwclock to "daily" folder:
mv /etc/cron.hourly/fake-hwclock /etc/cron.daily

5. Edit samba startup script (add ram folder for tmp files):
nano /etc/init.d/samba
# in start-command after first row "deamon..." add this:
mount -t tmpfs tmpfs /var/run/samba
mount -t tmpfs tmpfs /var/cache/samba
# in stop-command before "log_end_msg 0" add this:
umount /var/run/samba
umount /var/cache/samba

6. Increase dirty-writeback-time 5s to 60s
echo 6000 > /proc/sys/vm/dirty_writeback_centisecs

7. Reboot.

########
Check if all runing normall:
# Ramlog
/etc/init.d/ramlog status
# If not - read logs:
tail /var/log/ramlog

#ramlog is working with tmpfs? samba-mounts to tmpfs exists?:
df -h
