我正在尝试按照这些说明在兄弟模型中安装Squid。 但是，当客户端执行HTTP请求时，需要很长时间才能从服务器获得响应。
系统型号：
+---------+ +----------+ | | sibling | | | Squid 1 +----------+ Squid 2 | | | Net | | +----^----+ +-----^----+ | | | | +----+----+ +-----+----+ | Net 1 | | Net 2 | | | | | +---------+ +----------+ 我用以下选项运行鱿鱼：
$ sbin/squid -v --enable-cache-digests \ --enable-htcp \ --enable-icmp \ --enable-async-io
squid.conf文件：

我用选项-Nd1执行鱿鱼，这里是cache.log。
