MySQL数据库INNODB引擎优化问题

Question

 CREATE TABLE `user` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `balance` int(11) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=108 DEFAULT CHARSET=utf8;

update user set balance = balance - 1     where id = ?

上面表结构，下面查询语句。表不大，只有上百条数据，但是高并发访问的时候会锁住。请问怎么优化？
