Hyperthreading allows a core to switch quickly to the other execution context when the current one is starving for IO (from network, disks or RAM...) or when it sleeps, without having to replace the entire instruction pipeline, and allows to switchback fast too when first thread is ready to work again.TrogloGeekhttps://www.blogger.com/profile/12775760605035881695noreply@blogger.comtag:blogger.com,1999:blog-933941164961652504.post-36454330570294637532017-06-21T04:59:06.509-07:002017-06-21T04:59:06.509-07:00"Hyperthreading can provide a marginal (10%) ... "Hyperthreading can provide a marginal (10%) for some server workloads ", that seems hyperthreading can only provide a small marginal . Then why when hyperthreading ENABLED,the cpuinfo would show twice processor items, which would give a fake impression of twice process power .Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-933941164961652504.post-44458562806597881972016-07-27T20:41:32.387-07:002016-07-27T20:41:32.387-07:00thanks, read again, finally I got itthanks, read again, finally I got itAnonymoushttps://www.blogger.com/profile/00806891443291252733noreply@blogger.comtag:blogger.com,1999:blog-933941164961652504.post-89356860794362753072011-11-22T12:58:04.987-08:002011-11-22T12:58:04.987-08:00If this was you tube i'd Like and Favourite!
