For large bandwidth The server How can I optimize to improve the performance of PHP server? According to statistics, 83.6% 's website runs in PHP. Therefore, for Web servers with large bandwidth, it is necessary to ensure good performance of PHP. You can implement PHP by optimizing large bandwidth servers, preventive maintenance and all-weather monitoring High response of large bandwidth servers. that How to optimize the performance of PHP servers for large bandwidth servers? Focus today Large bandwidth server rental The hosted Micron Network will take you to have a look, hoping to help you.
1、 Enable OpCode caching for large bandwidth servers
This could be PHP optimization is the simplest and most influential. Disk access costs are high. Each access includes script, template, layout and database records, which involve disk access. By enabling OpCodes like APC Cache, we have been able to reduce disk access by nearly 70%. That's because duplicate requests are provided from the cache running in system memory.
2、 Use fast PHP engine and handler
We have seen a lot The Apache Web hosted large bandwidth server runs PHP 5.6 by default, and mod_php is used as the handler. Mod_php runs PHP in each Apache process Interpreter. It increases the access memory usage of each site, and leads to high load on servers with large bandwidth. Most importantly, PHP 5.6 uses the old Zend engine, which is better than the latest PHP supported by the PHP NG engine 7. 95% slower. By using the PHP 7.2 engine and php fpm as handlers, we can see the best results for performance and security. By using PHP 7.2+php fpm +Nginx replaces the default combination of PHP 5.6+modPHP+Apache, and we have been able to increase the site speed by nearly 150%.
3、 Large bandwidth server optimizes database queries, tables and settings
Almost all PHP sites use MySQL database to store data. When troubleshooting website performance problems, we have tracked them to the underlying database many times. We see that slow queries, fragmented tables, and unoptimized settings slow down the database, which affects PHP site speed. Slow queries can only be fixed by rewriting the application code, which is very important for most Web Large bandwidth servers are not practical. In this case, we minimize the severity of the performance problem by using the opcode cache. However, we can improve the performance of the database bandwidth server itself through regular database bandwidth server audit and optimization. Some common settings we adjust are:
Innodb_buffer_pool_size The size of the buffer in the InnoDB database. Typically set to 50-70% of available memory. The buffer size of key_buffer_size MyISAM database. Typically set to 20% of available memory. Max_connections - The number of available connections per user. Affects memory usage per user. Query_cache_size - The total memory size used to save old queries.
4、 Use the SSD of the large bandwidth server for the database
The hard disk is the slowest component in a large bandwidth server. In the busy e-commerce hosting large bandwidth server, install the database directory in the On SSDs instead of mechanical hard disks, we have been able to reduce the performance lag by more than 50%. So, if you have tried everything and are stuck in heavy I/O, get a SSD。 For example, when selecting a domestic server with large bandwidth, you can select a 240G SSD hard disk or an additional SSD hard disk to achieve this operation.
5、 Isolate or limit memory
Not every PHP applications are equal. Some are good coding, performance analysis and performance tuning. Others are arbitrary coding and contain memory leaks. In a shared bandwidth server, PHP is usually poorly coded The site will lead to high load of large bandwidth servers. To prevent these sites from affecting other large bandwidth server users, we either set hard limits for their memory allocation or place them in virtual large bandwidth servers with hard resource limits. In this way, even if one or two sites misbehave, the vast majority PHP customers will also have a fast hosting experience.
In short, PHP Dominating the web hosting market, every web Large bandwidth servers need to be adjusted to provide the fastest hosting service. All cloud virtual large bandwidth servers have been optimized through the above settings to improve PHP Performance. All the above settings are the skills we learned in the process of providing an ultra fast PHP hosting experience. I hope it is helpful to you.
