Preload files to memory

[namtih]

I want to share a little modification, which brought the biggest improvement in overall handling for me until now. The idea was to automatically preload some important files to the memory after the system startup - like for example the databases.

Someone called it "a poor man's trick" as I only cat the files. So here it is:
1. nano /etc/rc.local
2. Insert before "exit 0"

Code:

#make an empty file to check if the commands were executed
touch /run/xstart_`date +%F_%T`
#preload database files (about 10mb for me)
cat /home/xbian/.xbmc/userdata/Database/*.db > /dev/null
#preload commoncache plugin if installed
cat /home/xbian/.xbmc/userdata/addon_data/script.common.plugin.cache/commoncache.db > /dev/null
#preload python files for youtube-plugin
cat /home/xbian/.xbmc/addons/plugin.video.youtube/*.py > /dev/null
cat /home/xbian/.xbmc/addons/plugin.video.youtube/*.pyc > /dev/null
#another empty file to check if all commands were executed and how long it took
touch /run/xstop_`date +%F_%T`

3. Do a reboot
4. check if the "xstart*" and "xstop*" got generated

Code:

ls -al /run/x*

As I said, the system feels much smoother while browsing through the lists, infoarts and addons. Hope you will also feel an improvement.

What could be other files worth preloading?
