Hi I was reading this article on installing asterisk 1.6 + debian http://www.howtoforge.com/installing-and-configuring-asterisk-1.6-and-postgresql-to-manage-cdr-and-realtime-config-on-debian and I noticed they suggested to recompile to 1000Hz enable kernel, I currently have a 250Hz stock standard kernel. I am running on a soekris board - amd geode cpu. Is recompiling the kernel to the 1000Hz going to be beneficial to me, the box is primarily used for firewall router / voip (Asterisk) Alex
Yes it will be beneficial. We have a TDM410P and were getting nominal performance until we recompiled the kernel. A good use of 6 hours. -----Original Message----- From: asterisk-users-bounces at lists.digium.com [mailto:asterisk-users-bounces at lists.digium.com] On Behalf Of Alex Samad Sent: Tuesday, June 23, 2009 4:10 PM To: asterisk-users at lists.digium.com Subject: [asterisk-users] 1000Hz kernel Hi I was reading this article on installing asterisk 1.6 + debian http://www.howtoforge.com/installing-and-configuring-asterisk-1.6-and-postgr esql-to-manage-cdr-and-realtime-config-on-debian and I noticed they suggested to recompile to 1000Hz enable kernel, I currently have a 250Hz stock standard kernel.

I think I noticed an improvement with dahdi_dummy audio mixing when using the 1000Hz versus 250. You wouldn't have known about this suggestion if you had never read that page, and asterisk will still run. I would call that particular suggestion a 'best practice', rather than a 'must do'.

The only reason to increase the kernel timer to 1khz is when you need dahdi_dummy module, which uses this timer to fake interrupts that otherwise would be generated by real hardware. -- Moises Silva Software Developer Sangoma Technologies Inc. | 50 McIntosh Drive, Suite 120, Markham ON L3R 9T3 Canada t. 1 905 474 1990 x 128 | e. moy at sangoma.com -------------- next part -------------- An HTML attachment was scrubbed...

Is there a demand for a backport of this to Zaptel? -- Tzafrir Cohen icq#16849755 jabber:tzafrir.cohen at xorcom.com +972-50-7952406 mailto:tzafrir.cohen at xorcom.com http://www.xorcom.com iax:guest at local.xorcom.com/tzafrir
