When looking at Marvel I am noticing that my response times have gotten really slow. I have all 3 beats running on a handful of servers and am collecting considerable amounts of data. Here are some screen shots showing timing when I view my indices in marvel ![](https://us1.discourse-cdn.com/elastic/original/2X/f/f155f0ed715692ef52977ed330463654c52147aa.png) Here are some other stats about my cluster Nodes: 5 Indices: 97 Memory: 3GB / 5GB Total Shards: 887 Documents: 234,149,993 Data: 92GB Version: 2.3.3 Also I have a dedicated master node with no data. My Kibana instance is connecting to that node. The beats indexes are separated out by beat type and day. Thanks for any tips! ---

So it looks like my instances were using the default 1gb limit for Java. I have upped this to 50% of the server size (4GB per node) and everything is running significantly faster. I thought it used 50% by default but looks like I was wrong ![](https://us1.discourse-cdn.com/elastic/original/2X/5/527dcd9d9d7ea621b7131c11306955171ecebca8.png) ---
