首先将以下代码加到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>
