今天IIS團(tuán)隊(duì)發(fā)布了Windows Cache Extension 1.0 for PHP的beta測(cè)試版,這是用來提高PHP應(yīng)用跑在Windows系統(tǒng)上的速度的PHP加速器。任何PHP應(yīng)用程序不需要修改任何代碼都可以用它來提速,所需做的只是在PHP引擎里啟用這個(gè)擴(kuò)展。

Windows Cache Extension 1.0 for PHP 5.2 - Beta
Windows Cache Extension 1.0 for PHP 5.3 - Beta

按照"Using Windows Cache Extension for PHP"文章里的指示來安裝、啟用和配置這個(gè)擴(kuò)展。

注意:

  • 該擴(kuò)展只能用于PHP的non-thread-safe版本
  • 該擴(kuò)展只能用于以FastCGI方式運(yùn)行在IIS上的PHP
  • Windows Cache Extension 1.0 for PHP 5.3只能用于PHP5.3的x86 VC9版本

特性:

  • 支持PHP 5.2和PHP 5.3
  • 提供PHP函數(shù)獲得cache狀態(tài)信息


該擴(kuò)展包含3個(gè)可以被分別啟用或禁用的緩存特性:

  • PHP opcode cache -PHP是一個(gè)腳本處理引擎,它閱讀包含文本和/或PHP指令的輸入流,并產(chǎn)生另一個(gè)數(shù)據(jù)流(通常是HTML格式)。這意味著在一個(gè)web服務(wù)器上PHP引擎對(duì)每一次來自瀏覽器客戶端的請(qǐng)求都要讀入、解析、編譯和執(zhí)行一遍PHP腳本。讀入、解析和編譯操作給web服務(wù)器的CPU和文件系統(tǒng)帶來額外的負(fù)載,影響PHP網(wǎng)頁應(yīng)用的總體效能。PHP opcode (字節(jié)碼) cache用來在共享內(nèi)存里緩存編譯好的腳本字節(jié)碼,以便同一腳本文件的后續(xù)請(qǐng)求可以被PHP引擎重用。
  • File cache-即使PHP字節(jié)碼緩存啟用,PHP引擎還需要訪問文件系統(tǒng)里的腳本文件。當(dāng)PHP腳本存儲(chǔ)在遠(yuǎn)程UNC文件共享時(shí),文件操作會(huì)帶來顯著的性能開銷。Windows Cache Extension forPHP的文件緩存可以把PHP腳本文件的內(nèi)容緩存在共享內(nèi)存里,減少PHP引擎的文件系統(tǒng)操作。
  • Relative file path cache-PHP腳本頻繁使用相對(duì)路徑include或操作文件。每個(gè)相對(duì)文件路徑需要被PHP引擎轉(zhuǎn)換成絕對(duì)文件路徑。當(dāng)PHP應(yīng)用以相對(duì)路徑使用很多PHP文件時(shí),解析相對(duì)路徑到絕對(duì)路徑的操作會(huì)影響性能。Windows Cache Extension forPHP提供相對(duì)文件路徑緩存,減少PHP引擎需要進(jìn)行的轉(zhuǎn)換數(shù)量。

What are the main pros and cons of Linux vs. Windows? What are the main pros and cons of Linux vs. Windows? Aug 03, 2025 am 02:56 AM

Linux is suitable for old hardware, has high security and is customizable, but has weak software compatibility; Windows software is rich and easy to use, but has high resource utilization. 1. In terms of performance, Linux is lightweight and efficient, suitable for old devices; Windows has high hardware requirements. 2. In terms of software, Windows has wider compatibility, especially professional tools and games; Linux needs to use tools to run some software. 3. In terms of security, Linux permission management is stricter and updates are convenient; although Windows is protected, it is still vulnerable to attacks. 4. In terms of difficulty of use, the Linux learning curve is steep; Windows operation is intuitive. Choose according to requirements: choose Linux with performance and security, and choose Windows with compatibility and ease of use.
