Node.js + Express.js very slow serving static files
提问by Chris
Sometimes when developing my current node project I will get a hanging refresh. Where the page will never load. I check the network tab in Chrome and see that its always hung up on a static files. The static file that gets stuck will differ, sometimes it will be a CSS file other times an image file.
有时在开发我当前的节点项目时，我会得到一个悬而未决的刷新。页面永远不会加载的地方。我检查了 Chrome 中的网络选项卡，发现它总是挂在静态文件上。卡住的静态文件会有所不同，有时是 CSS 文件，有时是图像文件。
I have tried to optimize all my files in hopes to resolve this issue but nothing has fixed it. If I hit refresh during a long load it will load the page correctly on the 2nd request. This does not happen every time I try to load the page but very often when switching between pages.
我试图优化我的所有文件，希望能解决这个问题，但没有任何解决办法。如果我在长时间加载期间点击刷新，它将在第二次请求时正确加载页面。这不会在我每次尝试加载页面时发生，但在页面之间切换时经常发生。
If I disable cache under the chrome network inspector, It will almost always happen.
如果我在 chrome 网络检查器下禁用缓存，它几乎总是会发生。

I had exactly the same issue. I just moved to a place with a pretty bad internet connection. Loading time of static files in my node.js app increased to more then 40s per file.
我有完全相同的问题。我刚搬到一个互联网连接很差的地方。我的 node.js 应用程序中静态文件的加载时间增加到每个文件 40 多秒。
I just moved the static middleware
我只是移动了静态中间件
app.use(express.static(__dirname + '/public'));
to the top of app.configure function, before all the other app.* calls.
到 app.configure 函数的顶部，在所有其他 app.* 调用之前。
It's now working significantly faster.
现在它的工作速度明显加快。

I spent about 3 hours last night trying to solve this problem. I found that there was a while statement that was slowing the page down terribly:
我昨晚花了大约 3 个小时试图解决这个问题。我发现有一个 while 语句严重减慢了页面速度：
while ((incomingUsername !== "") && (incomingPassword !== "")){
newAccount(incomingUsername, incomingPassword);
}
function newAccount(name, password){
console.log("ACCOUNT REGISTRATION INITIATED");
}
When I commented out the while statement, the page loaded in a matter of seconds.
当我注释掉 while 语句时，页面会在几秒钟内加载。
