Systeminformation.graphics This function will cause high CPU utilization

[BlockCnFuture]

Describe the bug
When calling the Systeminformation.graphics function, especially when calling it within an interval, you will see high CPU utilization.

To Reproduce
Steps to reproduce the behavior:

1. used function 'Systeminformation.graphics' in Interval, call it every two second

Current Output
This function will cause high CPU utilization

Expected behavior
Should not cause high CPU utilization

Additional context
This problem is probably caused by using promise.all to execute multiple PowerShell commands concurrently under Windows. You can change it to execute one by one. The execution will not be much slower, but the CPU utilization problem should be optimized a lot.

@BlockCnFuture Yes, on Windows the overhead calling Opening a PowerShell process is really high. I do not suggest calling this every 2 seconds. I already mentioned the whole situation in this issue: #616

For version 6.0 I am working on something where we spin up a pool of PowerShell processes and they can then be used by each function ...

@sebhildebrandt Do you also not recommend calling every second graphics if si.powerShellStart(); is used? What is currently the right way to monitor GPU metrics every second?

[sebhildebrandt]

@TheRedfoox You are right, even when using si.powerShellStart() this is to often. This function needs a few seconds to get everything for the underlying window commands. Unfortunately this is all much slower in windows that in macOS or Linux.

[TheRedfoox]

@sebhildebrandt I did not find a way to call only some GPU metrics (only GPU usage) that allowed to lighten the call. Do you confirm to me that it is not possible at the moment or did I miss something in the document?

[sebhildebrandt]

@TheRedfoox Yes I can confirm that (for now). The only way would be probably to write C++ or C# code ...
