How Schedule Qboost Memory Optimization... for Emby

[Hispanico957 23]

Since even asking QNap support they don't give info/help to be able to use the utility, after several attempts I succeeded and I explain how:

- using WinSCP  or Filezilla etc. create a "Nas" folder (or name of your choice) in share/CACHEDEV1_DATA
- create a .sh file in the folder (which I called cache) using the nano or Vi editor with the following content and save it

#!/bin/sh
/share/CACHEDEV1_DATA/Nas/cache.sh

using Putty in SSH mode go to the folder and type the following command to make the file executable

chmod +x cache.sh

then with the editor nano open crontab

nano /etc/config/crontab

and insert the following lines at the bottom of the list

0 19 * * * /share/CACHEDEV1_DATA/Nas/cache.sh
0 21 * * * /share/CACHEDEV1_DATA/Nas/cache.sh
0 23 * * * /share/CACHEDEV1_DATA/Nas/cache.sh

which means that QBoost (or clear cache utility) starts every day at 19, 21 and 23.

save the crontab file modified in this way and then give the following command to reload the crontab file:

crontab /etc/config/crontab && /etc/init.d/crond.sh restart

This utility and routine is very important using an Emby server on my QNAP, which uses a lot of memory when using.

Attached is a before and after example

HI, thanks for sharing.

Sorry but I mistyped the command in the .sh file (cache.sh) and here below I report everything correctly and revised:

- using WinSCP  or Filezilla etc. create a "Nas" folder (or name of your choice) in share/CACHEDEV1_DATA
- create a .sh file in the folder (which I called cache) using the nano or Vi editor with the following content and save it

#!/bin/sh
/bin/echo 1 > /proc/sys/vm/drop_caches

using Putty in SSH mode go to the folder and type the following command to make the file executable

chmod +x cache.sh

then with the editor nano open crontab

nano /etc/config/crontab

and insert the following line at the bottom of the list

0 19-23/2 * * * /share/CACHEDEV1_DATA/Nas/cache.sh 

which mean that QBoost (or clear cache utility) starts every day at 19, 21 and 23 (every 2 hours)

save the crontab file modified in this way and then give the following command to reload the crontab file:

crontab /etc/config/crontab && /etc/init.d/crond.sh restart
