WordPress slow的Docker

问题：

我对WordPress&Docker有一个问题，因为我的网站加载速度慢（+-7秒）。我不知道为什么会发生这种情况，但我认为这与外部数据库或共享卷有关

设置：

我有一个自定义Dockerfile，它是用XDebug和Mailhog在WordPress上构建的。此docker文件包含在my docker-compose.yml中，docker compose包含的其他服务包括WP-CLI和Mailhog。我的数据库托管在Amazon RDS上，因此我可以与同事共享

代码：

我的Dockerfile如下所示：

FROM wordpress:latest

# Plugins & Media
RUN mkdir -p /var/www/html/wp-content/plugins
RUN mkdir -p /var/www/html/wp-content/uploads

RUN chown -R www-data:www-data /var/www

RUN find /var/www/ -type d -exec chmod 0755 {} \;
RUN find /var/www/ -type f -exec chmod 644 {} \;

# Mailhog
RUN curl --location --output /usr/local/bin/mhsendmail https://github.com/mailhog/mhsendmail/releases/download/v0.2.0/mhsendmail_linux_amd64 && \
    chmod +x /usr/local/bin/mhsendmail

RUN echo 'sendmail_path="/usr/local/bin/mhsendmail --smtp-addr=mailhog:1025 --from=noreply@examle.com"' > /usr/local/etc/php/conf.d/mailhog.ini

# Xdebug
ENV XDEBUG_PORT 9000

RUN yes | pecl install xdebug \
    && echo "zend_extension=$(find /usr/local/lib/php/extensions/ -name xdebug.so)" > /usr/local/etc/php/conf.d/xdebug.ini \
    && echo "xdebug.remote_enable=1" >> /usr/local/etc/php/conf.d/xdebug.ini \
    && echo "xdebug.remote_autostart=1" >> /usr/local/etc/php/conf.d/xdebug.ini \

但我不明白为什么它这么慢；我得到了Docker Desktop的2.1.09.3版，并在快速Mac或Windows上工作

有人能帮我或给我指出正确的方向吗

编辑

如果我查看docker统计数据，我的CPU大约为0.01%，内存大约为2.73%，所以这不会是问题所在

发现最大的问题是连接到外部数据库。如果移到本地数据库，加载时间会快得多（+-1秒）

Mac和Windows卷性能存在一些问题

Mac和Windows有一些我们应该考虑的。

我更改了我的

docker compose.yml

注意，因为我改变了

此符号允许添加一致性选项

我添加了

wp content

和

php conf

（以获取php.ini），因为它们是每次在浏览器中加载Wordpress页面时最常调用的文件目录

wordpress：

同样的问题，您解决了吗？类似的问题：@Yanick当您使用docker开发时，是否使用Mac或Windows？这是否回答了您的问题？虽然此链接可以回答问题，但最好在此处包含答案的基本部分，并提供链接供参考。如果链接页面发生更改，仅链接的答案可能无效。-@克里斯，谢谢你的评论。我想补充信息是个好主意。我这样做是因为我注意到这个问题可能是重复的，我不知道假设在哪里是重复的问题。现在我注意到关闭选项。
