Hi,Thanks for the replies so far.
Walter: We have a few more solr cores. So the JVM is sized accordingly. I know
we can separate the cores but for easier maintainability we have only one core.
Also only one core is being used majority of the times.
Jorn: I dont have a particular performance
You should not have other processes/container running on the same node. They
potentially screw up your os cache making things slow, eg if the other
processes also read files etc they can remove things from Solr from the Os
cache and then the os cache needs to be filled again.
What performance
Reading all the documents is going to be slow. If you want to do that, use a
database.
You do NOT keep all of the index in heap. Solr doesn’t work like that.
Your JVM heap is probably way too big for 2 million documents, but I doubt that
is the performance issue. We use an 8 GB heap for all of
