We did test with out application - (running more than 10 tomcats  
using F5s for Load balancing) and came to the belief that we could  
deal with 15% more users online at the same time. As I said, though,  
this was OUR application - maybe yours is different...

For our purposes however we also found Intel 5160s packed more punch  
per $ than AMD Opterons - (Thankfully we don't have to worry about  
paying the power bills in our colocation)...
