我正在做一个执行各种事情的ajax请求，并且它需要永远加载。在进行了一些挖掘以找出瓶颈所在之后，我发现使用Eloquent构建查询的速度非常慢。
这是我正在构建的原始查询：
SELECT
`events`.`id`,
FROM_UNIXTIME(
EVENTS.event_datetime,
"%a %D %b %H:%i"
) AS DATETIME,
CONCAT(
countries.name,
" ",
leagues.name

CONCAT(
EVENTS.team1_name,
" vs ",
EVENTS.team2_name
) AS game,
CONCAT(
eo1.value,
" <a href=\"#\" class=\"add-bet\" data-id=\"",
eo1.id,
"\"><i class=\"fa fa-plus\"></i></a>"
) AS home,
CONCAT(
eo2.value,
" <a href=\"#\" class=\"add-bet\" data-id=\"",
eo2.id,

) AS draw,
CONCAT(
eo3.value,
" <a href=\"#\" class=\"add-bet\" data-id=\"",

CONCAT(

CONCAT(

) AS under,
CONCAT(
"<a href=\"#\" class=\"expand-all btn\" data-id=\"",
EVENTS.id,
"\"><i class=\"fa fa-plus\"></i> Expand all odds</a>"
) AS expand,

我正在以雄辩的方式建造它：

if(!empty($order) && !$sort) {

if($sort) {

->orWhere('events.team2_name', 'LIKE', "%".$search['value']."%")

}
或者我可以将它构建为一个大字符串，而不是：
$query = '

如果我使用eloquent来构建查询而不执行它需要1.899秒，而如果我使用字符串方法需要0.006秒。
我更愿意使用雄辩，但我无法像这样表现出色，我能做些什么来加速用雄辩的方式构建查询？
