Hello community member,
I want create query related tips for optimize performance and reduce overhead in Ray tasks but i have no idea that witch category is best for my query. Actually I am new in this forum website so I have no idea witch category is best for my query.
If have any idea please suggest me. It will be appreciate. 
Thank you for my help.
Welcome Amara to #rayfam ^_^. Since you’re using Tasks directly probably Ray Core is the right category.
That aside can you share some more details on what you’re trying to do and where you are seeing overhead?
Is it startup time; execution time, are you seeing slow spin down of Ray Tasks, Nodes, Autoscaling, inefficiency in min/max node configurations (the list goes on)?
@Sam_Chan Thank you for you guidance.
