Hi everybody, we're facing performance problems - as mentioned weeks ago. Even if they aren't critical, sometimes it's really annoying. I think the most probable guilty is NFS export/mount, but maybe I am wrong. I am writing in order to collect opinions and ideas to work on.
Here's the scenario: Client A with RDAirPlay and playout system, server B with MySQL and audio share (NFS exported). On the client we use a special keyboard like this http://www.tipro.net/ecatalogue/64-programmable-keys. Every key is associated to a key-shortcut (like CTRL+SHIFT+E or whatever). Ubuntu catches the combo and execute a .sh file, containing a rmlsend command. Most of them are sound panel start/stop or Next command. A bit complicated but works. >From the moment we press NEXT button (on our keyboard) to the moment we actually hear sound, *sometimes* it takes like 3-500ms... But (!) if we pre-listen the song (double click on the left side of RDAirPlay), then when we will press NEXT it will start almost immediately, as it were moved in cache and got ready to be played. Do you think this delay is avoidable? Do you think it is a Linux (Ubuntu) problem? Not-RealTime kernel? Or a NFS bad configuration? How do you set your exports/mount? Any idea will be appreciated. Thank you Alessio www.poliradio.it
