Update, download a MP with this script here, Contoso.Write.File.to.Share
I have written a script that writes a line of text to a file on a share. It will then return the time it took in the strTimer parameter. You can use this script to measure the time it takes to write text to a file on your network. The default share is \\10.1.1.10\share. You can also change the loop (default 1500) to write the text line more times to the file, that would result in a test with a larger file.
