bind9 on debian

JJX · 03-22-2013, 06:14 AM

Hello all,

I have installed bind9 from Debian official repositories.
Bind9 is supposed to support multiprocessor (if is compiled so).
I am running bind as "/usr/sbin/named -u bind -n 8 -4"
However, only one core is used at 80%

* Does anyone know how is compiled the debian package?
* How can I know if debian bind9 supports multiprocessor ?

Thank you

"top -H" will show you threads, if there's more than one for named it'll be capable of taking advantage of multi-processors.

You may run:

Code:

rndc status

Running bind with option -g , first lines will show compile options:

built with '--prefix=/usr' '--mandir=/usr/share/man' '--infodir=/usr/share/info' '--sysconfdir=/etc/bind' '--localstatedir=/var' '--enable-threads' .....etc......'

Although it is compiled with thread support, only one core is used...
