We are moving away from our legacy version of elasticsearch 2.0 (with marvel and alerting) to 5.0 with xpack.
I was wondering what is an easy and good way to performance test elastic? I want to see how it affects the performance from upgrading, and to see if the xpack plugin requires us to have a better servers because of the additional plugins.
Our server configuration as of now:
3x machines (1 node per machine) with 4 cores and 32GB of ram
I am looking to change that to:
each machine have 3 nodes, using containers. each node will have 2 cores and 9GB of RAM. What do you think?
