This article explains how to speed up PHP database interactions by using persistent connections, implementing a connection pool, and caching query results, providing clear code examples for each technique to improve overall efficiency.
This article explains how to speed up PHP database interactions by using persistent connections, implementing a connection pool, and caching query results, providing code examples for mysqli, PDO, and Memcached, and discusses when each technique is appropriate for improving backend performance.
To accelerate PHP database operations, the article explains how to use persistent connections with mysqli or PDO, implement a connection pool via a custom class, and cache query results using Memcached or Redis, detailing code examples for each technique.
This article explains the PHP pfsockopen() function, its parameters, return values, and provides a complete example demonstrating how to establish a persistent SSL socket, send an HTTP POST request, and read the response using low‑level socket operations.
This article explains the step‑by‑step process from entering a URL to page rendering, focusing on TCP connection reuse, HTTP persistent connections, pipelining, HTTP/2 multiplexing, SSL session reuse, and browser limits on simultaneous connections for pages with many images.
The article explains how modern browsers manage TCP connections for HTTP requests, covering persistent connections, the number of requests per connection, pipelining limitations in HTTP/1.1, the advantages of HTTP/2 multiplexing, SSL reuse, and browser-imposed limits on concurrent connections per host.
The article explains how modern browsers handle TCP connections and HTTP requests—including persistent connections, the limits on simultaneous connections per host, the (disabled) HTTP/1.1 pipelining, SSL reuse, and how HTTP/2 multiplexing improves image loading performance.
