最近在写一个symfony程序,最开始是直接在Mac下通过console server:run命令启动一个简单的web服务器来访问,但是Mac本身自带的php没有memcached扩展,所以就把这个程序放到vagrant中,然而发现访问的速度非常慢,一个极其简单的页面也需要消耗10秒左右,于是搜索了一下,发现之前有人遇到相同的 问题。
vagrant环境中symfony程序速度慢解决方案
该文章中列出的几个方案: http://leo108.com/pid-2196.asp
- 使用vagrant1.2版本(目测不合适,现在都已经1.7+了)
- 使用NFS方式挂载目录
- vagrant虚拟机中的Vbox Guest Additions版本与virtual box版本一致(我当前的环境就是一致的)
- 使用opcache扩展(我当前的环境已经安装了apc)
- 关闭xdebug和xphrof扩展(我当前环境已经关闭)
看这情况,只能尝试一下NFS方式了,根据vagrant的 文档配置,还好OS X自带了nfsd,省去了安装的麻烦,只需要修改vagrantfile即可。
symfony
在vagrantfile中增加两行:
http://leo108.com/pid-2196.asp
config.vm.network :private_network, type: :dhcpconfig.vm.synced_folder ".", "/vagrant", type: "nfs"
然后重启vagrant虚拟机vagrant reload

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.
