Measuring file server performance can be a little tricky. In this post, we are going to look at each of the components that affect the speed clients can read/write to a file server. After gathering baseline stats, we'll look at 2 different ways to test the performance of a file server: using the Windows Explorer file copy UI and using the diskspd command line tool. We'll find that the speed shown in the Windows Explorer file copy interface isn't a reliable measurement of the disk throughput on the backend.
