Subject Re: Slow nodetool response time

Sounds like your process is spending a lot of time in blocked state (real -
user - sys). Check your os subsystems, maybe your machine is bogged down by
other work.

FWIW, my time in an idle system is about 2 seconds but can go up to ~13
seconds on a busy system with 70% cpu utilized. No difference between 1 and
3 node setups.

All the best,
