Planning for rolling out our products or capacity planning for large instances is better suited for service offerings than Atlassian Support. We will refer this kind of activity to our partner network. This includes establishing specific upgrade and deployment plans for existing installations.
We suggest customers run the Performance Testing Scripts available for products to see how well their software instance performs given the
hardware, configuration in use and expected workload. Using this data, the instance can then be tuned for performance should there be any issues encountered.
It is also recommended that you closely monitor your production instance to ensure that performance does not degrade as your instance grows in size.
Atlassian does not have provide benchmarking data at this time.
