GetWorkflowExecutionHistory is taking a long time

Hi Team,

We are observing a high response time for this api "gRPC/temporal.api.workflowservice.v1.WorkflowService/GetWorkflowExecutionHistory
" Reaching upto 15 to 20sec in many instances.

However this api gRPC/temporal.api.workflowservice.v1.WorkflowService/StartWorkflowExecution
is working as expected and taking less than 50ms

Can you please help us with this.
