Question

在用户列表中，我有一个头像。当我这样写：

<img src="{{ $user->avatar }}" class="img-circle img-sm"/></a>

75位用户的脚本需要17秒。

但是当我写道：

<img src="{{ "/images/avatar/avatar.png" }}" class="img-circle img-sm"/></a>

它很快。

为什么这个属性如此耗时？

在这个页面中，我从这个对象中调用了很多属性，但只有这个属性很耗时...它只是字符串更多......

我在Laravel 5.3

编辑：粘贴全表：

<table class="table datatable-responsive" id="table{{ $championship->id }}">
    <thead>
    <tr>
        <th class="min-tablet text-center "
            data-hide="phone">{{ trans('core.avatar') }}</th>
        <th class="all">{{ trans('core.username') }}</th>
        <th class="phone">{{ trans('core.email') }}</th>
        <th align="center" class="phone">{{ trans_choice('categories.category',1) }}</th>
        <th align="center" class="phone">{{ trans('core.paid') }}</th>
        <th class="phone">{{ trans('core.country') }}</th>
        @can('edit',$tournament)
            <th class="all">{{ trans('core.action') }}</th>
        @endcan
    </tr>
    </thead>


    @foreach($championship->users as $user)
        <?php
        $arr_country = $countries->where('id', $user->country_id)->all();

avatar属性是否与另一个表有关系？它可能是foreach内的延迟加载问题。
