how to test read and write performance in caliper

My smart contract includes following function:

1. three functions have query ability: function1,function2,function3
2. three functions have update ability: function4,function5,function6

How can I test query ability and update ability(throughout) overall?

I try to invoke all three query functions in submitTransaction(), but it gets calling function1,function2 and function3 serially...something doesn't feel quite right
