NetBench is a portable benchmark program that measures how well a file server handles file I/O requests from 32-bit Windows clients, which pelt the server with requests for network file operations. NetBench reports throughput and client response time measurements. To run NetBench, you need a file server, a PC running Windows NT/2000 or Windows XP (called the controller) to start and monitor the tests, and clients that are running Windows 95/98, Windows NT/2000, or Windows XP.

●Procedure:

1. Mount disk to DUT and partition disk. [Operate on terminal]

1.1 Plug indatawireandpower cable correctly, assure system run normally.51Testing软件测试网*R4k"\'x-k`3`r

1.2 To get the disk information with command “fdisk -l”. You can find that the disk is identified or not by system. If find, the terminal will prompt the disk information, e.g.:/dev/sda.51Testing软件测试网 WV@6?5FfQY$e

1.3 Partition disk with command “fdisk /dev/sda”. You will create partial “/dev/sda1”. (Detail information about command “fdisk”, please refer to man help.)51Testing软件测试网)Q:E@*g%hr5]uh~

If not, you should check the network and hosts file, and then restart the NetBench Client. If it is OK, please go on. (Note: you can run five NetBench client instance on one client PC in the meantime, do not run more than it.)

10. Now the test suite will be executed. One suite has several scrīpts. Each scrīpt will add the DUT load by increasing client number, and meanwhile keeping the other parameter no change. Executing the scrīpt setting one by one, at end of the test, the ball will become red. It means that the test is over.

Not luckily, we maybe prompt error information by NetBench at initialization. We should identify that what error is normal and what is critical. And you can choose stopping or continuing. If it is critical one, you should stop the test suite and check your system setting to ask yourself some question, such as: network is OK or not, HDD is clean or nor, DUT can normally run or not, the test equipments are OK or not, etc, And also you maybe restart the whole system (include DUT and all the client). I think it needs more time and patient to assure the test go on normally.51Testing软件测试网]/oOZ1w

We focus on the summary sheet.The summary have two diagrams, one is Throughput, the other is Average Response Time. The two diagrams will be used in the performance report.51Testing软件测试网0cD N8Zp3C"G7l
