Hyperthreading is a technology used by processors to improve their performance by allowing them to handle multiple threads of instructions simultaneously. While hyperthreading can improve processor performance, it can also introduce latency in some cases.
Hyperthreading allows a single physical core to run multiple threads simultaneously, which can improve performance by utilizing unused processing resources.
For example, Intel’s Hyper-Threading Technology includes a feature called “Resource Allocation Technology” (RAT) which helps manage shared resources between hyperthreads to minimize contention and improve performance.
While hyperthreading can improve performance by utilizing unused processing resources, it can also introduce additional latency due to resource contention and scheduling overhead.
