The cpu is too high. Can you tell me why

[3 node cluster] cpu: 40 core client connection : 700 ~ 2000 read / write : 1K~2K

currently cpu usage 70 ~ 80%

What troubleshooting have you done? Can you give us the last few log lines in your aerospike.log? Do you have disk backed namespace? Why do you expect it to be lower? How big are your records? Without knowing any of the details, you may want to try generating a flamegraph [CPU Flame Graphs](https://www.brendangregg.com/FlameGraphs/cpuflamegraphs.html#Instructions) to get some clues where to look!
