Mysql Cakephp 3.0中的分页计数查询

我对cakephp 3.3版中的paginate的

count（）

有一个问题：

我的桌子上有60万条记录。 这里涉及的字段是

name

和

cityf

。两者在MySQL中都有索引

我显示的是10和10，尽管查询速度非常快，但paginate的

count（）

花费了50多秒

如何在cakephp的3.3版中解决这个问题。遵循以下两条SQL语句和时间：

选择查询主目录：

SELECT 
  Rr.id AS `Rr__id`, 
  Rr.idn AS `Rr__idn`, 
  Rr.aniver AS `Rr__aniver`, 
  Rr.pessoa AS `Rr__pessoa`, 
  Rr.name AS `Rr__name`, 
  Rr.phoner AS `Rr__phoner`, 
  Rr.tipolf AS `Rr__tipolf`, 
  Rr.addressf AS `Rr__addressf`, 
  Rr.num_endf AS `Rr__num_endf`, 
  Rr.complem AS `Rr__complem`, 
  Rr.bairrof AS `Rr__bairrof`, 
  Rr.cityf AS `Rr__cityf`, 
  Rr.statef AS `Rr__statef`, 
  Rr.cepf AS `Rr__cepf`, 
  Rr.n1 AS `Rr__n1`, 
  Rr.n2 AS `Rr__n2`, 
  Rr.smerc AS `Rr__smerc`, 
  Rr.n3 AS `Rr__n3`, 
  Rr.n4 AS `Rr__n4`, 
  Rr.fone AS `Rr__fone`, 
  Rr.numero AS `Rr__numero` 
FROM 
  `MG` Rr 
WHERE 
  (
    Rr.name like 'MARCOS%' 
    AND Rr.cityf like 'BELO HORIZONTE%'
  ) 
ORDER BY 
  name asc 
LIMIT 
  10 OFFSET 0

=10毫秒

说明：

id  select_type     table   type    possible_keys   key     key_len     ref     rows    Extra   
1   SIMPLE  Rr  range   NAME,CITYF,cityfbairrof,cityfaddressf,cityfbairrofaddressf,namen1n2n3n4     NAME    63  NULL    21345   Using index condition; Using where

id  select_type     table   type    possible_keys   key     key_len     ref     rows    Extra   
1   SIMPLE  Rr  range   NAME,CITYF,cityfbairrof,cityfaddressf,cityfbairrofaddressf,namen1n2n3n4     NAME    63  NULL    21345   Using index condition; Using where

- 选择查询计数：

SELECT 
  (
    COUNT(*)
  ) AS `count` 
FROM 
  `MG` Rr 
WHERE 
  (
    Rr.name like 'MARCOS%' 
    AND Rr.cityf like 'BELO HORIZONTE%'
  )

=51.247毫秒

说明：

id  select_type     table   type    possible_keys   key     key_len     ref     rows    Extra   
1   SIMPLE  Rr  range   NAME,CITYF,cityfbairrof,cityfaddressf,cityfbairrofaddressf,namen1n2n3n4     NAME    63  NULL    21345   Using index condition; Using where

id  select_type     table   type    possible_keys   key     key_len     ref     rows    Extra   
1   SIMPLE  Rr  range   NAME,CITYF,cityfbairrof,cityfaddressf,cityfbairrofaddressf,namen1n2n3n4     NAME    63  NULL    21345   Using index condition; Using where

在其他几种情况下也会发生这种情况：查询的计数总是非常慢

谢谢你的帮助

更多信息：例如，如果我只输入字段名，计数查询也很快，但是如果添加其他（字段cityf），计数查询非常慢）。有一个解决方案可以绕过分页计数，但它在3.0版cakephp中不起作用。。。我真的需要使用分页，如果可以绕过计数，只显示下一步按钮是一个解决方案。如何在cakephp的3.3版中做到这一点？也许这会有所帮助：。它讨论了MySQL和COUNT（）的性能问题COUNT是多少？
