Question

我尝试优化查询，以便通过以下查询获得更好的响应时间

SELECT * FROM `videos` 
WHERE MATCH (name,tags) 
AGAINST ('toto' IN BOOLEAN MODE) 
ORDER BY `id` DESC, `id` DESC  LIMIT 8

记录计数

Loading Time: Base Classes      0.0069
Controller Execution Time ( Engine / Search )   1.3354
Total Execution Time    1.3430

没有记录计数

Loading Time: Base Classes      0.0063
Controller Execution Time ( Engine / Search )   0.0147
Total Execution Time    0.0216

当我计算结果数量（对于我的分页系统）时，这是非常慢的

$query->get('videos')->num_rows();

任何解决方案？
