Add vizQL Server service and service.max_procs in tableau
Hello everyone,
I want to ask about my tableau dashboard which sometimes experiences very slow loading. Currently I have 3 tableau server nodes, with the following specifications for each node:
Node1
CPU: 32 Cores
Memory: 256GB
Storage: 250GB
Node2
CPU: 32 Cores
Memory: 256GB
Storage: 250GB
Node3
CPU: 32 Cores
Memory: 256GB
Storage: 250GB
And the service process configuration on each node is as shown in the image I attached.
And I have a problem where some of my dashboards experience slow loading when viewed by the user.
Do I need to add a vizQL Server service process on each node from 2 vizQL server services to 4 vizQL Server services on each node?
Then, do I check the service.max_procs parameter on the tableau server, for the service.max_procs parameter I have a value of 8 (default).
With the tableau server specifications that I have, do I have to change the service.max_procs parameter value? How do I determine the service.max_procs value?
Are there any other suggestions regarding settings to speed up the dashboard load in tableau?

Tableau Server 2019.1 Connector for AWS Athena Installation Help
I'm trying to connect Tableeau Server 2019.1 on AWS Linux 2 to AWS Athena.
I've searched for a good bit on to find installation instructions and have put together that the JAR file needs to be in the /opt/tableau/tableau_driver/jdbc directory.
I'm not sure if Open JDK 8 works or not so I switched to Oracale JAVA 8 64-bit just in case.
I have the server working on an automated install from CloudFormation complete with copying the Athena JAR file AthenaJDBC42_2.0.7.jar to the .../jdbc directory.
I restarted Tableau Server and even after all that if I create a new project and goto connections I can't seem to get the Athena connector to show up.
Does anyone have suggestions or a link to where there are instructions on how to do all these steps to get Tableau Server 2019 to connect with AWS Athena?
