Encaixes do WP de XCache e de eAccelerator atualizados

Nós terminamos apenas uploading as versões as mais atrasadas de nossos encaixes de XCache e de eAccelerator, agora na versão 0.6.

Para aqueles de você que faltou anúncio inicial, nós escrevemos dois encaixes isso deixou WordPress comunicar-se diretamente com os esconderijos variáveis memory-resident do opcode PHP que são usados em XCache e em eAccelerator impulsionar o desempenho e diminuir a atividade do I/O.

eAccelerator e XCache é o opcode mais-popular da abr-fonte dois que caching os motores para PHP, e nós recomendamos altamente que alguns e todos os anfitriões o usam melhorar o desempenho de PHP por diversas dobras. No detalhe, nós recomendamos XCache para o mais melhor desempenho.

Movimento do usuário terminado - tecnologias de NeoSmart Optimized inteiramente!

Nós temos trabalhado em mover-se para um usuário novo toda a semana, e nós terminamos apenas a transição. Melhor de tudo, nós temos comutado aos usuários novos sem nenhum downtime in-between. Nosso usuário novo é 1.86 um Duo do núcleo 2 do gigahertz e com o 3GB da RAM DDR2 - todos os agradecimentos aos guys awesome e galões em Lunarpages, o mais melhor anfitrião lá é.

Os muitos do trabalho entraram nesta transição nas esperanças de levantar o desempenho - e mais importante, a confiabilidade - de nosso usuário. No ano passado (desde que nós começamos primeiramente nosso hospedar com LP), nós fomos de diverso milhão batidas um o mês às dúzias dos milhões, e nosso usuário velho fêz exame completamente de uma batida. A essa extremidade, nós focalizamos em desdobrar o código de pouco peso e elevado-optimized toda ao redor; esperançosamente não haverá não mais downtime inesperado… sempre.

Nossa instalação atual do software é muito complicada, mas esperançosamente far-nos-á exame de toda a maneira a 0.00 minutos do downtime - que é nosso objetivo! Nós temos usuários múltiplos e programas da aplicação que funcionam no fundo cada um que faz que ele melhor - em vez do tradicional t--correia-usuário---toda maneira. No momento em que, nós temos atualmente uma pilha do software compreender de um engranzamento do apertado-knit destes produtos:

FastCGI for IIS Final Released, Congratulations to the IIS Team!

Congratulations are in order for Microsoft’s IIS development team - today they’ve just announced the public availability of the final version of the IIS-FastCGI ISAPI Extension - a long-awaited and much-improved way of running just about any open-source scripting engine on IIS, safely and quickly.

This FastCGI module for IIS 5.1, 6, and 7 (with Windows Vista and Server 2008) have been in the works for quite a while now, and we’ve been using them since the first beta release - they’re good. While the biggest benefit will be seen in using FastCGI w/ IIS7 to take advantage of the new kernel-mode caching, it’s still a huge improvement over the old way of running scripting engines for languages like PHP on Windows.

The Problem: Most open-source scripting engines like PHP and Ruby on Rails were initially developed on/for the *nix world. On Unix-based platforms, the easiest way of creating multi-threaded applications is just to run the same app twice or more (The CGI model). On Windows, that doesn’t work out so well, because it takes a lot more resources to create another process. So these engines released Windows-specific single-process multi-threaded engines; the only problem was, they weren’t stable. Too many race conditions in some very non-thread-safe code wreaked havoc on many Windows systems, with the PHP developers themselves giving “Stability on IIS” the lowest level of concern.

eAccelerator PHP Extension Isn’t Thread-Safe…

For all the Windows-bound PHP users out there, consider yourselves warned: even if you’re running the (supposedly) thread-safe PHP Win32 binary redistribution, you’re still susceptible to PHP Access Violation Errors, race problems, heap corruption, and much worse if you use the popular eAccelerator opcode-caching extension.

We did our testing with the binaries compiled by SiteBuddy using the latest versions of both PHP and eAccelerator. Almost immediately after initiating a stress test on our test servers we experienced the dreaded “PHP Access Violation” error - which brings down the entire IIS Worker Process to its heels.

Install PHP under Apache and Vista

I initially tried the msi installer for PHP 5. Unfortunately, it installs only PHP under CGI, which although it has some performance and security issues, might be ok for a quick and dirty development environment.

But the installer is badly broken. You’ll get an error something like

PHP Fatal error:  require_once()[function.require]: Failed opening
required 'SAM/php_sam.php' (include_path='.;C:php5pear') in
sam_factory on line 1

After fighting this for a couple of hours, I ended up installing manually anyway. I used this procedure to get PHP 5 running under Vista:

  1. Install the Apache webserver.
  2. Get the current version of PHP 5 from http://www.php.net/downloads.php#v5. (It’s 5.2.3 at this time). Get both the zip file and the PECL zip file (which includes extensions).
  3. Uninstall any previous installations of PHP 5 (Start > Control Panel > Programs and Features). You may have to reboot your machine.
  4. Disconnect from the Internet. Turn off your firewall. Turn off your virus checker.
  5. Turn off User Account Control (UAC).
  6. Get an administrator prompt by going to All Programs > Accessories. Right-Click “Command Prompt†and choose “Run as Administratorâ€
  7. Use the command prompt to manually remove directories containing previous PHP installations (like C:\Program Files\PHP…)
  8. Go to the directory where you’ve downloaded
