Bottleneck Analysis
Bottleneck – A point or component of a process where throughput is the slowest.
Understanding where time is spent
Elapsed Time = Running + Waiting
Key is the waiting - what type of wait(s)?

Disk I/O Bottleneck Analysis
Monitor and identify I/O bottleneck
Resource Monitor & Performance Monitor
MDW
DMV & Extended Events
What is driving high I/O load?
Inefficient query plan
Too much data to read/write
Slow I/O subsystem

Resource Monitor
File level I/O throughput and disk response time
