How to view and refresh dns cache in Linux
Mar 07, 2024 am 08:43 AM
DNS (DomainNameSystem) is a system used on the Internet to convert domain names into corresponding IP addresses. In Linux systems, DNS caching is a mechanism that stores the mapping relationship between domain names and IP addresses locally, which can increase the speed of domain name resolution and reduce the burden on the DNS server. DNS caching allows the system to quickly retrieve the IP address when subsequently accessing the same domain name without having to issue a query request to the DNS server each time, thereby improving network performance and efficiency. This article will discuss with you how to view and refresh the DNS cache on Linux, as well as related details and sample code. Importance of DNS Caching In Linux systems, DNS caching plays a key role. its existence

Advanced Usage of PHP APCu: Unlocking the Hidden Power
Mar 01, 2024 pm 09:10 PM
PHPAPCu (replacement of php cache) is an opcode cache and data cache module that accelerates PHP applications. Understanding its advanced features is crucial to utilizing its full potential. 1. Batch operation: APCu provides a batch operation method that can process a large number of key-value pairs at the same time. This is useful for large-scale cache clearing or updates. //Get cache keys in batches $values=apcu_fetch(["key1","key2","key3"]); //Clear cache keys in batches apcu_delete(["key1","key2","key3"]);2 .Set cache expiration time: APCu allows you to set an expiration time for cache items so that they automatically expire after a specified time.
The relationship between CPU, memory and cache is explained in detail!
Mar 07, 2024 am 08:30 AM
There is a close interaction between the CPU (central processing unit), memory (random access memory), and cache, which together form a critical component of a computer system. The coordination between them ensures the normal operation and efficient performance of the computer. As the brain of the computer, the CPU is responsible for executing various instructions and data processing; the memory is used to temporarily store data and programs, providing fast read and write access speeds; and the cache plays a buffering role, speeding up data access speed and improving The computer's CPU is the core component of the computer and is responsible for executing various instructions, arithmetic operations, and logical operations. It is called the "brain" of the computer and plays an important role in processing data and performing tasks. Memory is an important storage device in a computer.
Caching mechanism and application practice in PHP development
May 09, 2024 pm 01:30 PM
In PHP development, the caching mechanism improves performance by temporarily storing frequently accessed data in memory or disk, thereby reducing the number of database accesses. Cache types mainly include memory, file and database cache. Caching can be implemented in PHP using built-in functions or third-party libraries, such as cache_get() and Memcache. Common practical applications include caching database query results to optimize query performance and caching page output to speed up rendering. The caching mechanism effectively improves website response speed, enhances user experience and reduces server load.
APCu Best Practices: Improving the Efficiency of Your Applications
Mar 01, 2024 pm 10:58 PM
Optimizing Cache Size and Cleanup Strategies It is critical to allocate appropriate cache size to APCu. A cache that is too small cannot cache data effectively, while a cache that is too large wastes memory. Generally speaking, setting the cache size to 1/4 to 1/2 of the available memory is a reasonable range. Additionally, having an effective cleanup strategy ensures that stale or invalid data is not kept in the cache. You can use APCu's automatic cleaning feature or implement a custom cleaning mechanism. Sample code: //Set the cache size to 256MB apcu_add("cache_size",268435456); //Clear the cache every 60 minutes apcu_add("cache_ttl",60*60); Enable compression
