hostgator的问题是MysqL的版本.他们使用旧版本并使用“information_schema”延迟.
我的解决方案是评论“information_schema”的整个调用,这不是理想的但是有效.

该文件的路径是：{my_app} /vendor/cakePHP/cakePHP/src/Database/Schema/MysqLSchema.PHP

public function describeForeignKeysql($tableName,$config)
{
    /* Commented by hsoberon to fix the delay in HOSTGATOR */ 
    // $sql = 'SELECT * From information_schema.key_column_usage AS kcu
    //     INNER JOIN information_schema.referential_constraints AS rc
    //     ON (
    //         kcu.CONSTRAINT_NAME = rc.CONSTRAINT_NAME
    //         AND kcu.CONSTRAINT_SCHEMA = rc.CONSTRAINT_SCHEMA
    //     )
    //     WHERE kcu.TABLE_SCHEMA = ? AND kcu.TABLE_NAME = ? AND rc.TABLE_NAME = ?';

    // return [$sql,[$config['database'],$tableName,$tableName]];
}

这样延迟就得到了解决,一切都运转良好.至今.
