Article Title: Making PHP websites run faster-how to optimize PHP. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
PHP is a programming language that runs very quickly, but it is worth optimizing PHP itself than just optimizing code.
This article will explain why opti
items that we can change, one is the quality of the thumbnail, and the other is the size of the thumbnail image. The quality of the changed thumbnail determines the size of the generated Thumbs.db file, and the size of the thumbnail determines how quickly the thumbnail is displayed when viewed as thumbnails. Appropriate modifications may be made as necessary. It is recommended that the image quality should not be modified too low, the thumbnail size to 48 on it, too small can not see clearly.

exactly what Google's V8 JavaScript engine supports. In this way, you can use these built-in methods to manipulate the collection directly on the server side.
9. Use Nginx in front of Node
Nginx is a small lightweight WEB server that can reduce the load on your node.js server. You can configure the static resources on the Nginx rather than on Node. You can compress the response with Gzip on the nginx to make all the responses smaller. So, if you ha
node. JS benefits from its event-driven and asynchronous features, which are already fast. However, in the modern network is only fast is not good. If you're going to use node. js to develop your next Web app, then you should fair bet and make your app faster and surprisingly fast. This article will introduce 10, after testing that can greatly improve Node application skills. Don't say much nonsense, let's

Note: If you are using Windowsme and the following operating system, you can download "MagnaRAM97" to optimize the physical memory and virtual memory, so that the effect is better! In addition, the author recommends that you do not use the so-called optimization and collation of memory software!
Third, reasonable placement "shortcut"
Most of the time, we run the software is usually the software "shortcuts" To do, the hard disk is growing, the ins

Click "Start" gt; "Run" gt; Type "sysedit" gt; Find "System.ini" in its [386ENH] add: com2buffer= 1024 (indicates a cache size of 1024K) The cache size can be adjusted appropriately based on the actual memory size. according to the above settings, your Win98 is not run faster, of
Make your PHP 7 faster (gcc pgo)
We have been committed to improving the performance of PHP 7. Last month we noticed that the gcc pgo can improve the performance by nearly 10% on Wordpress, which made us very excited.
However, PGO, as the name suggests (Google can be used for Profile Guided Optimization), needs some use cases for feedback, that is, the Optimization needs to be bound to a specific scenario.
Cyber security seems to have been a hot topic, but people often focus on how to prevent hackers from hacking into servers, databases, and other sensitive issues, but often ignore routers in their homes. Nowadays wireless routers are widely popularized in the home, but some vendors are not paying enough attention to firewall and attack protection ability. The security of routers has become increasingly prominent, hackers are unscrupulous to steal user privacy, stealing bank accounts, to the Inter

It can be seen that Wordpress 4.1 is currently on this machine, and the QPS of the homepage can reach 1116.48. that is, it can process so many requests to the homepage every second,
Now, let's start to teach GCC and let him compile PHP7 that runs Wordpress4.1 faster. First, we need GCC 4.0 or later versions, but I suggest you use a version of GCC-4.8 or above (all GCC-5.1 now ).

Development trends: How much does the rapid development platform know?First, what is the rapid development platformIn short, it is the platform that can make development faster. When the development platform has been generated, although the programmer has reduced the number of programming time, but many development platforms to add links to describe the effect is not very good, such as some development plat
YesThe use of Windows 7 has become a great joy for many computer users. Compared with the previous Vista system, WindowsThe 7 system is really nice, fast, and easy to use, but do you worry about your own Windows 7 system, just like installing other Windows systems, just as it just started to run fast, as time increases, the efficiency will decrease? It is not difficult to keep your Windows 7 system running directly. The following describes ten effecti

Now, let's start to teach GCC and let him compile PHP7 that runs Wordpress4.1 faster. First, we need GCC 4.0 or later versions, but I suggest you use a version of GCC-4.8 or above (all GCC-5.1 now ).
The first step is to download the source code of PHP 7, and then do./configure. there is no difference between these.
Next there is a difference. we need to first compile PHP7 so that it can generate an exec

3. Reasonably place "Shortcuts"
In most cases, the software we run is usually implemented in a "shortcut" of the software, the hard disk is getting bigger and bigger, and more software is installed, many friends like to put shortcuts on the desktop, which will not only make you dazzled, but also reduce the system performance, and cause the system to become unstable due t
there is no abnormal situation, you will set it to half of the physical memory and then run those large software, if there is an exception, you need to increase the value of virtual memory properly! By analogy, When you find the best value, just set the value to the C disk on the OK!:

Ubuntu16.04 update the kernel-using more than 4.6 of the kernel will make the Dell computer with a card faster-and uninstall excess kernel, ubuntu16.044.6
Tips: I am a Dell a-card computer. I feel less fluent than fedora when using 16.04 desktop. Later I manually upgraded to the 4.6.2 kernel and found that I can perform smooth operations with fedora and windows desktops.

We've been working to improve PHP7 performance, and last month we were very excited to note that GCC's PGO can bring nearly 10% performance improvements on WordPress.
However, PGO as the name says (Profile guided optimization interested in Google), he needs to use a few use cases to get feedback, which means that the optimization needs to be tied to a particular scenario.
Your optimization of a scene may backfire in another scenario. It is not a generic optimization. So we can't simply inclu
