I've started using AMI Broker recently and have been taking advantage of its neat optimization feature. Unfortunately on my old AMD XP 3000+ system, it takes a LONG time to run through some of my optimizations (DAYS!) I'm looking to upgrade to maybe a Dual core system, but heard that AMI Broker will not run any faster on a dual core system because it isn't multithreaded. Does anybody know if this is true? What kinds of systems are people out there using with AMI Broker with good performance?
