Question

我将以下jsp部署到WAS，我在其中使用Federated存储库配置了LDAP。

<%@page import="com.ibm.websphere.security.UserRegistry"%>
<%@page import="com.ibm.websphere.security.Result"%>
<%@page import="java.io.PrintWriter"%>
<%@page import="javax.naming.InitialContext"%>
<%@page import="java.util.*"%>

<html>
<head>
<title>
test user's group
</title>
</head>
<body>
<%!
String group = "my_test_group";

%>
<%

String req = request.getParameter ("group");
if (req != null) {
group = req;
}

%>
<form method="post" action="<%=request.getRequestURI()%>">

Enter Group Name:<input type="text" value="<%=group%>" name="group"/><br>
<input type="submit" value="submit"/>

</form>
<br>
<%

InitialContext ctx = new InitialContext();
UserRegistry userRegistry = (UserRegistry) ctx.lookup("UserRegistry");
try {
        long start = System.currentTimeMillis();
        Result result = userRegistry.getUsersForGroup(group, 0);
        long end = System.currentTimeMillis();
        List list = result.getList();
        out.println ("call took " + (end - start) + " milliseconds<br>");
        out.println (list.size() + " users for " + group + "<br>");
        for (int i=0;i<list.size();i++) {
        String name = (String) list.get(i);
        out.println (name + "<br>");
        }
}
catch (Exception e) {
    PrintWriter pw = new PrintWriter (out);
%>
    There was an error getting the users for the group <%=group %><br>
    <pre>
        <%
        e.printStackTrace (pw);
        %>
    </pre>
    <%

}
%>
</body>
</html>

当我通过WebSphere点击这个jsp时，对于我的一些LDAP组，我没有得到大约150s +的响应。现在有趣的是，当我从同一个WAS主机直接对LDAP运行相同的查询（使用LDAP浏览器查询）时，我得到次秒的响应时间。

JSP代码是在做一些奇怪的事情吗？或者做一些奇怪的事情或两者兼而有之？非常感谢任何想法/指示。

Websphere用户注册表可以让用户获得组性能/延迟
