Laravel真的这么慢吗? [英] Is Laravel really this slow?

问题描述

我刚刚开始使用Laravel.我几乎还没有编写任何代码，但是我的页面要花近一秒钟的时间加载！

I just started using Laravel. I've barely written any code yet, but my pages are taking nearly a second to load!

当我的无框架应用程序和NodeJS应用程序耗时约2毫秒时，这让我有些震惊. Laravel在做什么?这不是正常行为吗?需要一些微调吗?

This is a bit shocking to me when my framework-less apps and NodeJS apps take ~2ms. What's Laravel doing? This isn't normal behaviour is it? Does it need some fine-tuning?

推荐答案

Laravel实际上不是 那很慢. 500-1000ms是荒谬的；我在调试模式下将时间缩短到20毫秒.

Laravel is not actually that slow. 500-1000ms is absurd; I got it down to 20ms in debug mode.

问题是Vagrant/VirtualBox +共享文件夹.我没意识到他们招致了如此高的表现.我猜是因为Laravel有这么多的依赖项(可加载约280个文件)，并且每个文件的读取速度都很慢，所以加起来确实非常快.

The problem was Vagrant/VirtualBox + shared folders. I didn't realize they incurred such a performance hit. I guess because Laravel has so many dependencies (loads ~280 files) and each of those file reads is slow, it adds up really quick.

kreeves向我指出了正确的方向，此博客文章介绍了Vagrant 1.5中的一项新功能，该功能使您可以将文件重新同步到VM中，而不使用共享文件夹.

kreeves pointed me in the right direction, this blog post describes a new feature in Vagrant 1.5 that lets you rsync your files into the VM rather than using a shared folder.

Windows上没有本地rsync客户端，因此您必须使用 cygwin .安装它，并确保选中Net/rsync.将C:\cygwin64\bin添加到您的路径. [或者您可以在Win10/Bash上安装它]

There's no native rsync client on Windows, so you'll have to use cygwin. Install it, and make sure to check off Net/rsync. Add C:\cygwin64\bin to your paths. [Or you can install it on Win10/Bash]

Vagrant引入了新功能.我正在使用Puphet，所以我的Vagrantfile看起来有点有趣.我不得不对其进行调整以使其看起来像这样:

Vagrant introduces the new feature. I'm using Puphet, so my Vagrantfile looks a bit funny. I had to tweak it to look like this:

  data['vm']['synced_folder'].each do |i, folder|
    if folder['source'] != '' && folder['target'] != '' && folder['id'] != ''
      config.vm.synced_folder "#{folder['source']}", "#{folder['target']}", 
        id: "#{folder['id']}", 
        type: "rsync",
        rsync__auto: "true",
        rsync__exclude: ".hg/"
    end
  end

设置完毕后，请尝试vagrant up.如果一切顺利，您的计算机应启动，并应复制所有文件.您需要在终端中运行vagrant rsync-auto，以使文件保持最新状态.您需要支付一点延迟，但是值得将页面加载速度提高30倍！

Once you're all set up, try vagrant up. If everything goes smoothly your machine should boot up and it should copy all the files over. You'll need to run vagrant rsync-auto in a terminal to keep the files up to date. You'll pay a little bit in latency, but for 30x faster page loads, it's worth it!

如果您使用的是PhpStorm，它的自动上传功能甚至比rsync更好. PhpStorm创建了许多临时文件，这些文件可以使文件查看器跳闸，但是如果您让它自己处理上传的文件，则它将很好地工作.

If you're using PhpStorm, it's auto-upload feature works even better than rsync. PhpStorm creates a lot of temporary files which can trip up file watchers, but if you let it handle the uploads itself, it works nicely.

另一种选择是使用 lsyncd .我在Ubuntu主机-> FreeBSD guest虚拟机上使用它取得了很大的成功.我还没有在Windows主机上尝试过它.

One more option is to use lsyncd. I've had great success using this on Ubuntu host -> FreeBSD guest. I haven't tried it on a Windows host yet.
