Many thanks for the testing done so far. Hopefully it'll be of considerable use to the Asterisk community.

A possible future test:

What'd be very interesting to see is how Asterisk scales as hardware changes. For example, by what percentage do the call completion figures increase by switching to quad-core CPUs? Is it better to have slower quad-core chips, or faster dual-core chips?

Looking at the results, memory usage is fairly low, so one could reasonably deduce that 2GB RAM would be perfectly sufficient. Given that scenario, it'd be great to have some comparisons with different system specs to achieve the most "useful" system spec for a given budget.

Regards,

Chris
