       Imagine you receive an e-mail that looks something like this: ARE YOU GOING TO CLASS TODAY?
How does reading this message make you feel? Why did the sender use all capital letters? Was he or she
angry, or did that person just forget to turn off the 'Caps Lock' on the computer? The fact is, this e-mail
'sounds' like the writer is shouting because using all capital letters in an e-mail is usually the way that people
shout online.
        Knowing when and when not to use capital letters is just one example of online etiquette (规矩) often
called netiquette. Virginia Shea's book, Netiquette, lists a basic set of dos and don'ts for communicating
(交流) rightly with others online. Following are some of her suggestions. 
        First, always remember that you are sending messages to a real person, not just to a computer. Don't
type anything that you wouldn't say to someone's face. Also, remember that the person who receives your
message cannot hear the tone of your voice, or see the expression on your face, so make sure your meaning
is clear. 
       Don't do anything online that you wouldn't do in real life. Don't take anything without paying for it,
unless it's free. Don't use information that someone else has written, and say it's yours. Don't read other
people's e-mail-you wouldn't open your next-door neighbor's mailbox and open their mail, right? Do share
your knowledge of the Internet with others. It's a big place with lots of information, and there are many new
things to discover.
       Remember that people think about you by your words as well as your actions, so do try to write well.
Good writing skills, as well as correct grammar and spelling, do matter. Send polite, well-written e-mail
messages to others. If you're uncertain about how to spell a word or which phrase to use, look it up. There
are lots of helpful books and websites.
        It's okay to express your opinions online in forums like chat rooms or message boards, for example
"MSN" or "QQ", but don't start arguments with people. 'Flame wars' (网上论争) in online discussions can
be interesting to read, but are often unfair (不公平) to other members of the group. Express your ideas, but
remember that fighting (打架) on or offline is just not right. 
        When you're online, just as in 'real' life, try to respect other people's space, privacy, and feelings.
Remember, you're not the only one traveling on this highway!

试题四(25 分)  阅读下列说明,回答问题1 至问题3,将解答填入答题纸的对应栏内。【说明】  软件系统性能调优的关键是首先作好性能故障定位,面对软件系统中运行在不同平台上的多个服务器、多种应用、大量工作站以及局域网、广域网和其他类型的网络体系结构,故障点交错,故障定位测试非常复杂。下述是《工作流平台系统》的性能测试案例描述及结果数据:  ● 测试案例描述:模拟多用户登陆《工作流平台系统》,针对工作流A、B、C 分别连续创建20 个实例,在单机和集群运行环境下分别对系统进行负载压力性能测试。单机环境下测试用机与一台应用服务器连在同一交换机上,压力直接加在一台应用服务器上。集群环境下测试用机与服务器集群连接在同一交换机上,压力由负载均衡模块分摊到俩台应用服务器上。在单机和集群运行环境中应用服务器和一台数据库服务器连接。  ● 客户端交易并发执行测试数据:

  ● 服务器资源占用情况  1 单机运行环境  ①应用服务器资源占用情况

②数据库服务器资源占用情况

  2 集群运行环境  ①俩台应用服务器资源占用情况

②数据库服务器资源占用情况

【问题2】(10 分)  试分析系统应用服务器和数据库服务器资源使用情况如何?是否有瓶颈存在?单机运行环境和集群运行环境相比,哪种环境下资源占用率更高?为什么?随着系统并发负载的加大,试预测哪种环境下资源占用率递增更快?
