Sorry for the noob post, I'm diving into ES and runing a preliminary test. I can see a consistent performance drop every 10 minutes in both indexing and searching (monitoring with marvel). Server has 32GB RAM / 16 GB Heap for ES. No other settings differ from defaults. Can I presume is this the GC?
Is there a way to monitor when the GC is happening? Any other possible explanation?
PS: Centos 7.1, SAN disk, kvm virtualized environment in a dedicated server, no other processes running.
