One major drawback with CGI is that it launches a new program each time a user clicks on a form, so Web servers used for heavy traffic sites could be running thousands of programs at once -- a huge drain on Web-site performance.

• 用CGI的一大缺陷是每次用户点击一下表格就生成一个新程序，因而用于大流量网站的服务器可能同时运行数以千计的程序--极大地消耗了网站的性能。
