I have a customer currently using round-robin SLB on a 11503. They are looking at implementing Dynamic Feedback Protocol (DFP) agents to try to get more granular weighting for LB decisions. Has anyone used DFP, or are you familiar with the agents available for HP Blade Servers/Windows 2003 or other OS? Has it resulted in any performance gains? We don't want to waste to many cycles if it will not give us double digit gains in performance.
