discuz的新版本检测和补丁功能已经关闭，导致后台调用相关链接时超时，引起后台打不开

X3.4已经移除相关代码，没有此问题，建议升级

X3.4以下的版本速度慢的解决办法
后台
打开：source/admincp/admincp_main.php 删除代码：

if($_G['uid'] && $_G['member']['allowadmincp'] == 1 && ($_G['setting']['showpatchnotice'] == 1 || !isset($_G['cookie']['checkpatch']))) {

        $discuz_patch = new discuz_patch();

        if($_G['setting']['showpatchnotice'] == 1) {

                $notice = $discuz_patch->fetch_patch_notice();

                if($notice['data']) {

                        $shownotice = '<div class="notice"><a href="'.$basescript.'?action=patch" id="notice">'.($notice['fixed'] ? $lang['patch_fix_complete'] : $lang['patch_fix_rigth_now']).'</a></div>';

                }

        }

        if(!isset($_G['cookie']['checkpatch'])) {

                $discuz_patch->check_patch();

        }

}

if($_G['uid'] && $_G['member']['allowadmincp'] == 1 && !$shownotice && $_G['setting']['upgrade']) {

        $shownotice = '<div class="notice"><a href="'.$basescript.'?action=upgrade" id="notice">'.$lang['upgrade_right_now'].'</a></div>';

}

if($_G['uid'] && $_G['member']['allowadmincp'] == 1 && !isset($_G['cookie']['checkupgrade'])) {

        $discuz_upgrade = new discuz_upgrade();

        if($discuz_upgrade->check_upgrade()) {

                if(empty($shownotice)) {

                        $shownotice = '<div class="notice"><a href="'.$basescript.'?action=upgrade" id="notice">'.$lang['upgrade_right_now'].'</a></div>';

                }

        }

        dsetcookie('checkupgrade', 1, 7200);

}

前台也有影响管理员打开速度的
下载替换文件 source\module\misc\misc_patch.php
点击下载 misc_patch.zip(大小：770B)

也就是只保留IP异常提醒的代码，用不到也可以删了
