You completed certain nice points there. I did a search on the matter and found the majority of folks will have the same opinion with your blog.

Howdy,

Utility works just fine for me on an x86_64 AMD CPU on Ubuntu 10.04. Are you sure you’re actually on a 64-bit system?

Hi
The benchg729 utility doesn’t work for x86_64 architecture. I wrote the following command line.

# wget http://downloads.digium.com/pub/telephony/codec_g729/benchg729/x86-64/benchg729-1.0.7-x86_64 -O benchg729

# chmod 500 /root/benchg729

# /root/benchg729

And the error is:

-bash: /root/benchg729: cannot execute binary file

Why?

Then I tried with x84_32 architecture with the following commands.

# wget http://downloads.digium.com/pub/telephony/codec_g729/benchg729/x86-32/benchg729-1.0.7-x86_32 -O benchg729

# chmod 500 /root/benchg729

# /root/benchg729

And the result is:

Recommended flavor for this system is ‘prescott’ with an average of 593 milliseconds of CPU time.

But there isn’t a prescott version for x86_64 architecture

Does this resolve the bug where running a G.729 codec over IAX2 trunking can lead to 100% processor load?

Kevin didn’t mention this, but the new G.729 codec modules are also available on systems running AsteriskNOW 1.5 beta. If you have the existing modules installed, you can do a `yum update` to get the new ones, or `yum install codec_g729a` if you don’t.

It won’t select the best optimization for your CPU yet, but that is something I plan on working on.

Hi This is great, but it seems the test tool has a few issues.

see debug below.
