Threading The Needle Of Power8 Performance

I am going to take a break from the price/performance comparisons between earlier Power machines and the new Power8 systems and talk about something a little bit different from but still intimately related to the performance that customers can expect from the latest IBM i operating system releases as they run on the new iron and on older Power7 and Power7+ machines. The issue is threading, and IBM has done some pretty clever things to help the operating system and processors juggle more work and boost throughput.
Most modern processors have some form of simultaneous multithreading, or SMT,
