Re: [ros-dev] [ros-diffs] [dchapyshev] 41389: - Start services.exe and lsass.exe with above normal priority class

[Ged]

Ok, I've just read the actual code for NtSetInformationProcess (probably should have
done that first)
It's right, what threw me was your r41390 commit which contained this :

+    PriorityClass.PriorityClass = PROCESS_PRIORITY_CLASS_HIGH;
+    PriorityClass.Foreground = FALSE;
+
+    /* Set priority for process */
+    if (!NT_SUCCESS(NtSetInformationProcess(ProcessInfo.ProcessHandle,
+                                            ProcessPriorityClass,
+                                            &PriorityClass,
+                                            sizeof(PROCESS_PRIORITY_CLASS))))
+    {
+        DPRINT1("Unable to set process priority for winlogon.exe\n");
+    }

I assumed from reading this that our NtSetInformationProcess was setting process
priorities via #defines.
It turns out that the above is actually wrong. From pstypes.h :

#define PROCESS_PRIORITY_CLASS_HIGH 3

You were setting winlogon to have a priority of 3. Clearly not right ... heh.

Anyway, I see you've reverted it now. Problem solved.
I was just writing this follow up so you didn't start looking into
NtSetInformationProcess and scratching your head wondering what my previous mail was
about

Hi

This change is wrong. ABOVE_NORMAL_PRIORITY_CLASS sets them to a process level of 10 which
is too high.

Windows actually runs these at a level of 9 to ensure they get proc time before the
regular NORMAL_PRIORITY_CLASS(8) processes but below the ABOVE_NORMAL_PRIORITY_CLASS(10)
processes.

IIRC, you should be able to set the process directly using NtSetInformationProcess
although our implementation doesn't  seem to reflect this.
Is it our implementation or my memory which is wrong ?

Ged.
