首先将以下代码加到/usr/themes/handsome/libs/Content.php中，放在class Content{}之前

/*访问总量*/
     function theAllViews(){
             $db = Typecho_Db::get();
             $row = $db->fetchAll('SELECT SUM(VIEWS) FROM `typecho_contents`');
                 echo number_format($row[0]['SUM(VIEWS)']);
     }

    /*响应时间*/
    function timer_start() {
        global $timestart;
        $mtime = explode( ' ', microtime()  );
        $timestart = $mtime[1] + $mtime[0];
        return true; 
    }
    timer_start();
    function timer_stop( $display = 0, $precision = 3  ) {
        global $timestart, $timeend;
        $mtime = explode( ' ', microtime()  );
        $timeend = $mtime[1] + $mtime[0];
        $timetotal = number_format( $timeend - $timestart, $precision  );
        $r = $timetotal < 1 ? $timetotal * 1000 . " ms" : $timetotal . " s";
        if ( $display  ) {
            echo $r;
        }
        return $r;
    }

然后在/usr/themes/handsome/component/sidebar.php文件内，找到博客信息下面添加以下代码

<li class="list-group-item text-second"> <span class="blog-info-icons"> <i data-feather="users"></i></span>
<span class="badge
pull-right"><?php echo theAllViews();?></span><?php _me("访客总数") ?></li>
<li class="list-group-item text-second"> <span class="blog-info-icons"> <i data-feather="refresh-ccw"></i></span>
<span class="badge
pull-right"><?php echo timer_stop();?></span><?php _me("响应耗时") ?></li>
