In preferences.dat, set MaxDocProcessors greater than zero. Zero means no maximum limit as does a missing entry.
[MultiProcessing]
MaxDocProcessors=4
In preferences.dat, set CaptureSourceTimeSlice to your desired value in seconds. A missing entry means 180 seconds. Zero means (v8.6 onward) no template context switching.
[MultiProcessing]
CaptureSourceTimeSlice=180
In preferences.dat, set ProcessIsResponsiveTimeout to your desired value in seconds. A missing entry means 300 seconds. Negative values and alpha numerics are illegal. Zero means that no responsivity measure will be in effect. All other values smaller than 60 defaults to 60 seconds. Available from v8.6.0 onward.

ProcessIsResponsiveTimeout=300
In preferences.dat, set DetailedLogging to zero. A missing entry means zero in v7.6.0 and one in v7.6.1+. Only works in v7 from v7.6.0
[Network]
DetailedLogging=0
In preferences.dat, set HigherConnectionPriority to one. A missing entry means zero. Only works in v7 after v7.5.3. This will elevate the connection thread by one sub priority level placing it exactly midway between Normal and Above Normal.
[Network]

In preferences.dat, set AcceptSocketCount to a number greater that the expected total connections. A missing entry means zero. Zero or less means 4096. Part of all HPN releases.
[Network]
