We have a Kibana instance in a server with 4 cores and 8GB of RAM. At first, Kibana was running smoothly, but now it's feels very slow.

We see that Kibana it's not using all the CPU and RAM available.

How we can tune the CPU, RAM, etc. for best performance?

@dbonnin

Do you have info regarding resource usage in kibana? Is it CPU or RAM limited or both? Which version of the elastic stack are you running?

Its more frequently the case that your elasticsearch cluster is performing slowly making Kibana appear slow. If this is the case performance can be restored either through appropriate resource assignment or query optimization.

Apparently, that was the case, we increased the RAM memory of the search nodes of elastics and Kibana returned to work without problems.
