There are only 4 cores, so load average load average: 6.17, 3.65, 2.81
is high, and I want to know about the detail that beam.smp is doing(I Know: These processes are responsible for monitoring and managing all other underlying server processes such as ongoing XDCR replications, cluster operations, and views.)?
Can I change the beam.smp thread numbers?
