Loading mRemoteNG takes longer than expected

[Glober777]

I've noticed that mRemoteNG takes significantly longer (tens of seconds) to start on one of our VDI hosts, while showing Loading mRemoteNG. Please wait... message comparing to some other machines that we run. I captured a trace using WPR and found out that a significant portion of time is spent for a WMI call in mRemoteNG.exe!mRemoteNG.App.Initialization.StartupDataLogger::GetArchitectureData() method:

Looking at the sources I revealed that the query expression is actually pretty simple one:

"SELECT * FROM Win32_Processor WHERE DeviceID=\'CPU0\'"

However, testing how long this query executes on different machines I discovered that the execution time is proportional to the number of CPUs that a machine has.

Expected Behavior

Startup experience should be quick

Current Behavior

The load time increases proportionally to the number of CPUs that a machine has

Possible Solution

Update the query to return only the fields that are necessary

Steps to Reproduce (for bugs)

Get a server with a bunch of CPUs (i.e. a VM with a lot of single-core vCPUs) and start the tool

Context

Once we've migrated the tool to a more powerful VDI host (previous had only 2 vCPUs), we started experience longer startup delay.
