I suppose you're using XBian config GUI running under Kodi, right?
That package manager is still very buggy, I was working on it last 2 weeks and fixed a lot of issues, but did not release that version right now.

Quote:2: the version instaled is 4.1 and it is unbelievably slow : using iotop and top i can see that the reason for being slow is not the disk or even the CPU (only 5% utilised) so i am not sure what the issues is.

Hence i unistalled the package and installed a newer version with these commands:
wget http://sourceforge.net/projects/bananapi/files/unrar_5.2.6-1.arm6_armhf.deb
sudo dpkg -i unrar_5.2.6-1.arm6_armhf.deb

This new version is much faster, I would say around 3 times faster. There is a small increase in CPU utilization but the read and write on the disk is now around 2MB/s instead of 400KB/s with the older version.

I hope this is helpful to someone, I am keen to get hear about other possible optimizations as the unpacking is still quite slow; I suppose if other users agree it would be good to include in the list of packages available (replacing the old version).

Good idea I will do some tests and if I can confirm your results, I will put this version to our repo
