Using Task Manager with 64+ logical processors

We talked about the new Task Manager in a previous post, and many of you have installed the Developer Preview and seen it for yourself. There was some interest on this topic so we thought we would take a moment to quickly share with you a feature that just showed up in our daily builds that you will be able to see for yourself in the future, in the Beta release.

The pictures below relate to a feature that server admins and people with access to mega-PC setups with lots and lots of logical processors often ask us about. One key thing to note up front is that here we are talking about logical processors, so if you have a system capable of hyper-threading, you will see multiple logical processors for each physical processor.

For those of you who have access to one of these many-processor systems, you know that the task manager CPU charts in Windows 7 have a few limitations:

  • Lack of real-time comparisons: When you are looking at a CPU graph for lots and lots of logical processors, it is the anomalies that are interesting. At scale, it is pretty hard to compare moving line graphs of a 60-second window of CPU utilization to understand what is going on.

  • Tiny graphs: When you get to the 64+ logical processor range, the graphs get pretty small. If you are trying to figure out which processors are being heavily used, you really have to squint to figure it out. When you get over 256 logical processors, you can barely read the charts at all.

  • Finding the processor ID: If you do identify an anomalous graph, there is no easy way to get the corresponding processor ID.
