Docker部署的Laravel应用加载缓慢问题排查求助

我正在开发一款测验应用，将Laravel应用部署到Docker后，发现应用加载速度极慢——一个包含5个输入框的表单页面加载耗时约7-8秒。

我知道这个等待时间过长，因为几周前我部署的另一款Laravel Docker应用运行速度很快，但现在无法再使用它。我怀疑问题可能出在.yml文件和Dockerfile中，但不清楚具体的配置问题。

由于我使用的是Windows 10 Home系统，无法在Docker界面中禁用Use the WSL 2 based engine (Windows Home can only run the WSL 2 backend)选项。

数据库运行正常，速度良好。笔记本电脑性能不存在问题，因为之前部署的应用运行流畅无卡顿。
