intel的大拿们,请教一个超线程的测试性能问题

对网络报文做分析,使用软中断rps hash分发不同流的报文到各CPU线程,atom D525的超线程很有用,加超线程每个核的性能提升80%,而i7(2715),加超线程对每个核的性能仅提升20% (这里的性能指吞吐量和时延)

采用rp sCPU掩码来确定报文是否分发给单个核还是分发给核的两个线程

问一个超线程性能的问题

对网络保温分析处理,使用atom D525 CPU, 软中断分发流到每个核 , 然后软中断分发流到每个核的每个超线程,性能提升约80%

换成i7 2715, 同样的操作,性能提升只有20%多点

这是为什么?

既然atom的超线程能够提升这么大的性能,有没有办法让i7的超线程能够也升这么大的性能?
