Exactly my thinking...
We are actually getting an Altix 350 very shortly to give it a "fry" ...
We shall not use SIPP only but instead use a serious of "real life" scenario

I am not an hardware expert, but from my understanding, total numaflex bus
speed
is 51GBbits (ie 6GBytes ~ ) and that is what makes it capable of 5000+ calls
:)
