in general, after 64GB it is indeed makes more sense to scale out rather that up, however the extra memory is always useful as it will be used for OS cache which in turn will speed up queries if relevant segments are cached by operating system.
Hi,
I'm looking for the same answer, then I found the below post on the knowledge center. I believe this can make things clear.
[Why is the SysMemoryUtilization so high on my Amazon OpenSearch Service cluster?]
https://aws.amazon.com/premiumsupport/knowledge-center/opensearch-high-sysmemoryutilization/
Most of the memory used by OpenSearch Service is for in-memory data structures. OpenSearch Service uses off-heap buffers for efficient and fast access to files. The Java virtual machine (JVM) also requires some memory.
