Zephyr for Jira - performance impact on Jira

Dear all,

We are planning to use this plugin in our organisation where we already have jira v8.12.1 (data centre version) hosted on two application server nodes with MS-SQL 2016 as database. Our testers strength would be around 500 and we have 5000 licenses for jira. We are keen to understand how this plugin would impact the performance of jira.

This ZFJ plugin would be used by our testing community in the organisation where jira already has 3500 users . We do not want this new usage of ZFJ bringing down the performance of jira which is currently stable in the organisation . Please help share your experience /inputs /recommendations/known constraints in ZFJ
