Well, actually it all depends on workload and scheduling. I believe ULE is expected to improve things quite a bit in scheduling department. However, even with ol'good SCHED_BSD we measured noticeable performance increase (15-25%) in CPU intensive real-world tasks with HTT enabled on 2-way SMP Xeon system. It was in 2004, both CPUs and schedules should have been improved since that time.
