Thanks for your response. The hardware I have now is not sufficient to set up a ramdisk (just 4 gb)... But memory is rather cheap nowadays. If i'd buf up the server with 8 extra gigs for use as a ramdrive, do you think that might be enough to record between 30-60 simultanious streams? Or should it be way more?
btw, I found this thread somewhere: http://lists.digium.com/pipermail/asterisk-users/2005-October/120930.html, but this is rather old info. Is this documentation still usefull? And if not, do you happen to have any idea/url/doc where I can find a bit less old info? thanks, robin On Wed, Oct 21, 2009 at 13:21, Zoaaaaa <zoach...@securax.org> wrote: > > > There are 2 issues i think, one is the seek time on harddisks and the > lack of a big buffer in Asterisk (saving 10 streams at the same time > will cause a loooot of random writes). > The other one is the interrupts being taken up by the harddisk. > > So an SSD might help, saving to an network drive might help (it moves > the issue to another server, where it might not cause a problem), > buffering to ram (but you will lack space). > The best solution depends on your exact hardware and the amount of > writes you want to do. > > Buffering to a ramdrive before moving it over NFS seems like the best > idea to me. > > Zoa > > Robin wrote: > > I'm having loads of problems with recordings, as in crappy audio > > quality and lost pieces of the recordings.
