There is a demo/trial environment where I’m trying to run many very small Solrs, each with a single core and only a few documents.
I limited the heap as much as I can without crashing due to OOM during the operations I require, via mostly trial and error. But it seems nowadays off-heap memory is as important as heap if not more, because even with a very limited heap, I’m noticing total memory usage creeping up to 3x-5x the heap amount. I’m wondering if you have any tips on how to run Solr with very little RAM and how to especially reduce all kinds of off-heap memory. -ufuk yilmaz —
