问答 用户登录异常缓慢，有没有调优的方法？

如题用户登录的时候异常缓慢，内存8G的服务器，登录超过10秒。发现控制台刷新大量的shiro 菜单信息。。。而且每次登录都会刷新，想问一下有没有什么可以调优的方法？

For example:> "select distinct a.* from sys_menu a,sys_role_menu b where a.id=b.menuId and  b.roleId in(select c.roleId from sys_user_role c,sys_role d where c.roleId=d.id and c.userId='a311c77170774b3682b66eaba9757bab' and d.disabled=false) and a.disabled=false and a.isShow=true and a.type='menu' order by a.location ASC,a.path asc"

走索引了吗？数据量多少，即使全表扫描应该也没多少数据的样子

@wendal 走了索引的。。。才1000多条数据，不过数据库是oracle xe。。。

这sql在数据库控制台跑耗时多久

@wendal 1秒不到 应该不是 sql的问题

    public final AuthenticationInfo getAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {

        AuthenticationInfo info = getCachedAuthenticationInfo(token);
        if (info == null) {
            //otherwise not cached, perform the lookup:
            info = doGetAuthenticationInfo(token);
            log.debug("Looked up AuthenticationInfo [{}] from doGetAuthenticationInfo", info);//看代码   貌似是    执行这个log的时候相当的慢。。。。。。
            if (token != null && info != null) {
                cacheAuthenticationInfoIfPossible(token, info);
            }
        } else {

        } else {

        }

自己来吧，应该是服务器性能跟不上 最后修改了shiro 相关 jar 包代码，所有log输出都取消掉了
路径 org.apache.shiro.realm.AuthenticatingRealm.java

日志导致慢??

可以把Sys_User的toString方法改一下嘛

@wendal 确实是log.debug导致的慢 注销过后，登录速度变回正常1秒。
