Schedutils is being merged with util-linux. Maybe you can convince
schedtool's upstream to talk with the util-linux people and get their
improvements to be merged?

How does it compare to schedutils which are already in Debian?

See #293691, basically schedtool is a little bit better since it:
- can manage all sched policies known to the linux kernel (chrt from 
schedutils package only knows about CHED_FIFO, SCHED_RR and SCHED_OTHER)
- one executable (schedutils has two, but used to be more) to query and set 
cpu sched params along with the cpu affinity (easy to remember ;-)
- last but not least, it has much better and exhaustive documentation

schedtool can be used to query or alter a process' scheduling policy
under Linux. Support for CPU-affinity has also been added and most recently
(re-)nicing of processes. Thus, schedtool is the definitive interface to
Linux's scheduler.

It can be used to avoid skipping for A/V-applications, to lock
processes onto certain CPUs on SMP/NUMA systems, which may be
beneficial for networking or benchmarks, or to adjust nice-levels
of lesser important jobs to maintain a high amount of interactive
responsiveness under high load.

If you don't know about scheduling policies, you probably don't want to
use this program - or learn and read "man sched_setscheduler".

Certain modes (as of this writing: SCHED_IDLE and SCHED_ISO) need a
patched kernel (such as Con Kolivas' -ck patchset, from
http://members.optusnet.com.au/ckolivas/kernel/)
