How to improve the speed of point in time recovery using mysqlbinlog?

I am backuping database by online backup percona xtrabackup and binlog. My data is about 16G. I scheduled to do a full backup by xtrabackup. Binlog is for point in time recovery. Backup is OK.

When I make a disaster plan, I make a try to test recovery. I see the restore of full backup is so quick. It is about 2 minutes. But when I do point in time recovery using binlog is so slow. It takes more 30 minutes.

This is the way I follow to do point in time recovery:

cat xtrabackup_binlog_info 
mysql-bin.000004        413             0-88-28524789

mysql-bin.000004 is also the lastest binlog.

sudo mysqlbinlog mysql-bin.000004 --start-position=413 | mysql -u root -p

This database is very critical. I need to recover as quick as possible. More 30 mins is so much. How to improve the speed of point in time recovery ?
