I am using opendistro 1.13.2 version and facing around 50% performance dip in search query when enabling the opendistro security setting compared to security disabled

Do you have any performance number for ODFE ? My believe is for any search query performance number will differ if security will be disabled. Can you please give a try with your test case

As you suggested will move to opensearch but could you confirm after disabling the security setting there is no difference in performance gap. Meanwhile I will try to test with latest opensearch.
