I am doing a little demo this week and it includes a simple SQL Server script to generate activity on the network while I demo SMB2 durability.
First, the database is created:
USE [Master]
GO
CREATE DATABASE [Sales] ON  PRIMARY
( NAME = N'Sales', FILENAME = N'\\FSA\SQLDB\Sales.mdf' ,
  SIZE = 2GB , MAXSIZE = 8GB, FILEGROWTH = 1GB )
LOG ON
( NAME = N'Sales_log', FILENAME = N'\\FSA\SQLDB\Sales_log.ldf' ,
  SIZE = 1GB , MAXSIZE = 2GB , FILEGROWTH = 10%)
GO
USE [Sales]
GO
CREATE TABLE [dbo].[Product]
(  
 [ProductId] [uniqueidentifier] DEFAULT NEWID() NOT NULL,
 [ProductName] [nchar](50) NULL,
 [ProductDescription] [nchar](3000) NULL,
 [ProductPrice] MONEY NULL
) ON [PRIMARY]
GO
Then, the script to keeps the database a little busy:
USE [Sales]
GO

WHILE (1=1)
  BEGIN
  TRUNCATE TABLE [Sales].[dbo].[Product]
  DECLARE @Record INT
  SET @Record=1
  WHILE @Record<=10000
  BEGIN
    INSERT INTO [Sales].[dbo].[Product]
    ([ProductName] ,[ProductDescription],[ProductPrice])
    VALUES ('Product ' + STR(@Record), 'Description ' + STR(@Record), @Record*100/3)
    SET @RECORD = @RECORD+1
  END
  SELECT COUNT(ProductID) as RecordsCreated FROM [Sales].[dbo].[Product]
END
Simple stuff. Just so SQL Server can generate some activity that can be shown in Task Manager's Network tab while other things happen... :-)
