How to monitor and manage CPU - Windows Server Capacity Management 101(8 of 12)

Hyper threading is splitting a single CPU core into a two logical processors, each of these processors can execute a separate piece of work. You will see one thread being the dominate thread and one processing when the other is stalled. There is some trade off with hyper-threading as it take time for the CPU to switch between threads, Some work will fit well with this such as multiple threads of light-weight work, and more heavy work that needs the whole power of a core to get through could work slower with hyper-threading.

Depending on the type of work Hyper-threading is not always beneficial, sometimes it is better to have cores not have hyper-threading into multiple threads as the jumping between threads can lower the throughput.

On Monday I'll take a closer look at Thresholds and Trends. In the meantime why not take our Capacity Management Maturity Survey and get your free 20 page report.
