Good morning!
We're experiencing rather very bad latency spikes on busy Linux
systems, for example if one machine is the jumphost (ssh -J) for a few
hundred connections, while at the same time handles CPU intensive
tasks.
Would RT/Linux SCHED_FIXED or SCHED_RR be of help in such a case, e.g.
put all ssh processes into the SCHED_FIXED scheduling class, with a
priority higher than the non-interactive compute processes?
Also, do I interpret it correctly that each forwarded TCP connection
has its own process?!
