ES Heap and CPU Usage - bigger is better?
Hey guys, i´l just want to ask here if anybody has some better experience with bigger java heap sizes than me. Our problem is that we only have 1 big server with 256 gb RAM and 64 for our ES system which indexes about 4-6k events/s. Actually i have running 3 instances, 2 with 32 GB java heap and slow HDD´s as target for older indices and 1 with 96GB java heap and fast SSD storage. I think about splitting the 96GB instance to 2 X 32 GB RAM because our server sometimes is running out of CPU and given to the ES documentation heaps larger 32gb lead to uncompressed pointers and so far to much higher cpu usage. what make me worry is that instances which that little RAM arent able to handle the indexing and search load(which is quite high). Anyone with some experience to share? Cheers Stephen -- You received this message because you are subscribed to the Google Groups elasticsearch group.

Cache API Commands - _nodes/_aliases
Hey guys, Is there actually a way that elasticsearch can cache some API requests in memory, so that they dont have to be loaded from disk every time? E.g. If you open a ES stored dashboard in Kibana, Kibana is execurting curl syslogserver:9200/_nodes and after that curl syslogserver:9200/index/_aliases?ignore-missing. Our problem is that these 2 commands may take 5-10 seconds to finish and so the user of kibana are reporting poor performance due to the long loading time of dashboards. On our server we have much more RAM than needed so storing queries/API commands in RAM would be very exciting for us. Thanks for response.
