我想用Varnish 4优化一个Odoo安装.Odoo使用Python / Werkzeug来提供HTML。 Odoo 8.0rc1和Varnish 4.0.1-2〜在Ubuntu 14.04上值得信赖。 Odoo / Varnish都安装在同一台服务器上。 通过使用ab的简单testing，我每秒得到117个请求，没有清漆（在端口8069上）和116个清漆。 在服务器端，我得到了稍微更多（10％）不使用光油的Odoo服务器。
有任何想法吗？
这是直接给Odoo的：

当你用你自己的默认的'vcl'replace时，Varnish是最强大的。 默认情况下，这是在/etc/varnish/default.vcl（debian）中configuration的。
您需要确保启动脚本引用该文件。
如果你打开它，你可以看到默认的代码。 基本上，你需要“清除”Cookie头，因为它是通过系统传递的，所以清漆实际上可以caching项目。
默认情况下，你至less要强制静态媒体（图像，JavaScript，CSS），如下所示：
sub vcl_recv { if (req.url ~ "\.(css|js|ico|png|gif|jpg|swf|jpeg|zip)$" || req.url ~ "\.js?ver\=*$" || req.url ~ "\.css?ver\=*$") { unset req.http.cookie; # Cookies not needed here return(lookup); } }
清漆文档是非常详细的，并进入如何做基本上你需要在VCL做的一切。 我强烈build议花几个小时阅读一下：
v3的文档： https ： //www.varnish-cache.org/docs/3.0/ v4： https ： //www.varnish-cache.org/docs/4.0/
具体来说，您可能需要“用户指南”。
清漆是惊人的强大，但你摆脱了你把它放进去！
祝你好运，如果你遇到任何问题，请不要犹豫，向我们提出更多的问题！
