 	The first command will create a MyISAM table 'sbtest' in a database 'sbtest' on a MySQL server using <option>/tmp/mysql.sock</option> socket, then fill this table with 1M records. The second command will run the actual benchmark with 16 client threads, limiting the total number of request by 100,000.
