How to preset Processor scheduling settings in TD?
These settings you can get to from Control Panel-->System-->Advanced-->Settings (Performance)-->Advanced (Processor scheduling section).
The Processor scheduling settings are mapped to the following registry value:
You can overwrite this value in the Registry Data section of the "Client / Server Runtime (Console)" component.
This binary mask value should be set to (or just include) 0x18 to optimize the system to use a greater share of processor time to run background services.
The mask can actually be tuned much more precisely with setting particular bits of the value. More info on the bits meanings can be found here.
For instance. Clicking Background services sets the value of this entry to 011000 (0x18), and provides for longer, fixed-length processor intervals in which foreground processes and background processes get equal processor priority.
