I can't answer that question. I know little about your install. Even if I *did* know a few more things about your install, I could only make a *guess* about how much heap you need, and I'd probably be wrong. https://lucidworks.com/blog/2012/07/23/sizing-hardware-in-the-abstract-why-we-dont-have-a-definitive-answer/ I did write down what I consider to be a good way to figure out a correct heap size, but it requires experimentation with your live system, which might cause disruption of your search service: https://wiki.apache.org/solr/SolrPerformanceProblems#How_much_heap_space_do_I_need.3F Thanks, Shawn
