b. Edit the way Windows 2000 handles quantum lengths

Many administrators are familiar with the option in Windows 2000 to either give equal processing time to foreground and background processes or to give foreground processes slightly high priority. However, there are ways to provide additional levels of granularity and flexibility to foreground and background processes. To do this, we need to edit the way Windows 2000 handles quantum lengths.

Microsoft uses the term "quantum" to refer to the minimum amount of time spent executing one thread before switching to another thread. These intervals are actually not set in stone; they can be adjusted to some degree. Depending on the kind of programs and services you're running, you may want to give preference and adjust quantum timings to something other than the default settings.

The variations to quantum settings allow for their lengths to be fixed or variable, long or short, and (as we originally knew) biased towards foreground or background processes. Variable-length quanta are useful if you have services that kick in and out and use a lot of CPU time in bursts.
