I use Elasticsearch on Ububtu for my Rails app. After starting Elasticsearch, my app take 30+ seconds to load.
Server: 8GB RAM.
Before starting Elasticsearch: 5-600MB RAM in use
After starting Elasticsearch: 2.5BG+ RAM in use
Noone is using the app. Nothing is being indexed.
Is this normal?
Are there a common rule to put Elasticsearch on a seperate server?
Any idea how to fix this?
