定时扣除用户过期积分，但平台用户量比较大，有没有好的解决方法？

最近网站实行用户积分过期制度，只保留用户近三月积分，三月前未使用积分进行扣除

但平台用户量比较大，感觉这样做会出问题，有没有好的解决方法？(windows iis服务器)

代码如下：

ignore_user_abort();

set_time_limit(0);

do{

$this->del_score();

sleep(24*3600);

}while (true);

private function del_score()

{

$date = to_date(to_timespan(to_date(TIME_UTC)." -3 month"),'Y-m-d');

// 近三月使用积分

$user_scores = $GLOBALS['db']->getAll("SELECT user_id,sum(score) as score FROM ".DB_PREFIX."user_score_log WHERE score<0 AND create_time_ymd > '".$date."' GROUP BY user_id");

// 扣除用户过期积分

$update_sql = "UPDATE ".DB_PREFIX."user SET score = score - CASE id ";

// 添加过期积分扣除日志

$insert_sql = "INSERT INTO ".DB_PREFIX."user (`user_id`, `score`, `account_score`, `mome`, `type`, `create_time`, `create_time_ymd`, `create_time_ym`, `create_time_y`) VALUES ";

foreach ($user_scores as $k => $v) {

// 总过期积分

$old_account_score = $GLOBALS['db']->getOne("SELECT account_score FROM ".DB_PREFIX."user_score_log WHERE user_id=".$v['user_id']." AND create_time_ymd<=".$date." ORDER BY id DESC LIMIT 1");

if($old_account_score > abs($v['score'])) // 过期积分未消费完

{

$arr[$v['user_id']] = $v['score'];

// 应扣除积分

$score = intval($account_score - abs($v['score']));

$update_sql .= sprintf("WHEN %d THEN %d ", $v['user_id'], $score);

// 账户现有积分

$account_score = $GLOBALS['db']->getOne("SELECT score - {$score} FROM ".DB_PREFIX."user WHERE id=".$v['user_id']);

$create_time = TIME_UTC;

$create_time_ymd = to_date(TIME_UTC,"Y-m-d");

$create_time_ym = to_date(TIME_UTC,"Ym");

$create_time_y = to_date(TIME_UTC,"Y");

$insert_sql .= "(".$v['user_id'].",-".$score.",".$account_score.",'积分到期未使用部分扣除',26,".$create_time.",'".$create_time_ymd."','".$create_time_ym."','".$create_time_y."'),";

}

continue;

}

$ids = implode(',', array_keys($arr));

$update_sql .= " END WHERE id IN ($ids)";

$insert_sql = substr($insert_sql, 0, -1);

$GLOBALS['db']->query($update_sql);

$GLOBALS['db']->query($insert_sql);

}
