Hello Sagi,

Hey Bart,

Did you run your test on a NUMA system ?

I did.

If so, can you check with e.g.
perf record -ags -e LLC-load-misses sleep 10 && perf report whether this
workload triggers perhaps lock contention ? What you need to look for in
the perf output is whether any functions occupy more than 10% CPU time.

I will, thanks for the tip!
