Subject: Running nfsd as SCHED_FIXED, SCHED_RR?

Hello!

As part of an experiment to reduce NFSv4 server latency we want to run
nfsd with SCHED_FIXED and SCHED_RR. While Debian has a "nice" value in
/etc/default/nfs-kernel-server, there are no controls for the
scheduler class or IO scheduler class

Is it actually possible to put all nfsd threads into the SCHED_FIXED
or SCHED_RR scheduler classes? Can I use ionice for nfsd?
