You would need to include info for everything that would live on the Solr instance ... but even that estimator can only provide you with a *guess* as to how much heap size you need, and depending on how you actually use Solr, it might be a completely incorrect guess. You've already been given the following URL in response to the initial question, and gotten other replies about why there's no way for us to give you an actual answer: https://lucidworks.com/blog/2012/07/23/sizing-hardware-in-the-abstract-why-we-dont-have-a-definitive-answer/ Testing and adjusting the actual live production system is the only way to be absolutely sure what your requirements are. Anything before that is guesswork. Thanks, Shawn
