Hi Arie, Thanks for your hints. I've already set the file/proc limits, but adopted the mount parameters. I've not set the journal_ioprio=4,commit=60 options (cause we don't have that much writes) but set the other ones. They increased the performance. As seen in Elastic HQ the Search - Query/Fetch times could be cut in half. Thats great!
