Try to disable the wordpress 4.3's REVISIONS

According to someone else said. I try to disable the wordpress 4.3's REVISIONS.
This is the second post.
You can disable the REVISION by adding the follow code in the wp-config.php
[php]

// don't save REVISIONS（except the auto save）
define('WP_POST_REVISIONS', false);

//keep all REVISIONS
define('WP_POST_REVISIONS', true);

// keep n REVISiONS
define('WP_POST_REVISIONS', 3);
[/php]
