How to configure Presto

I have installed presto on my cluster in order to perform some queries. I have 4 nodes with 16GB of RAM. I have followed the steps into configuring presto but when i ran a query it takes forever, much more time than the same query on Hive. So i think i have something wrong in my configurations.

I think maybe i the wrong values on my node.properties file in the properties query.max-memory and query.max-memory-per-node. Whats the correct values for this properties taking in account that i have 16GB of RAM in each node?

Thanks

You have found the correct properties you may need to tweak. But there is no "correct" value... It really depends on your data + queries. Could you provide a general summary of the data set and types of queries you're running?
