FastCGI
Fast and Reliable.
v1.0 released in Oct 2007
v1.5 released in Nov 2009
Consistent set of features across all IIS versions:
FastCGI in IIS 7.5 – new features included in OS
FastCGI in IIS 7.0 – install the FastCGI update (http://www.iis.net/expand/FastCGI)
FastCGI in IIS 5.1/IIS 6.0 – install FastCGI 1.5 extension
Recommended way of running PHP on Windows

FastCGI (cont.)
New features:
Auto-tuning of maxInstances
Automatic recycling of PHP processes when php.ini changes
Useful tips
Use latest version of FastCGI and turn on dynamic maxInstances and monitorChangesTo features
Increase InstanceMaxRequests value and match the value to PHP_FCGI_MAX_REQUESTS environment variable

PHP 5.3
PHP 5.3 improvements:
Using VC9 compiler (PHP 5.2 used VC6)
Optimized API calls (using Win32 instead of POSIX)
All PHP libraries built from the source code
Compatibility fixes
Windows builds are available at:
http://windows.php.net/
From: http://ilia.ws/files/Confoo2010_PHP53.pdf
“Substantial performance improvements on Windows (40% +)”

WinCache 1.0
PHP Accelerator optimized for Windows
Opcode cache
File cache
Resolve path cache
Download from:
http://www.iis.net/expand/WinCacheForPhp
Contributed by MS to PECL:
Source code on http://pecl.php.net/wincache/
Documentation on http://www.php.net/wincache/
BSD license
Contributions are welcome!

Why use opcode cache?
To serve index.php in WordPress, PHP has to read, parse, compileand execute more than 100 php files!

WinCache 1.0
Useful Tips:
Increase maxInstances or use dynamic maxInstances
Adjust file cache and opcode cache sizes. Use wincache.php to study cache usage
Keep wincache.chkinterval value high on production servers and low on development machines
Restrict access to wincache.php by using built-inauthentication or web server authentication

WinCache 1.1
Beta2 released in April 2010
Object cache – Compatible with APC APIs
WinCache session handler
File change notification support
Function hooks
Useful Tips:
Turn on user cache if application supports it
Port from existing code which uses APC’s object cache
Keep file change notification turned on
Turn on session handler if not running a web farm

SQL Server Driver for PHP
Thin layer over SNAC (ODBC)
Single functional layer with thin API layer on top
SQL Server Driver for PHP 1.1
SQL Server Driver for PHP 2.0
php_sqlsrv.dll
php_pdo_sqlsrv.dll
php_sqlsrv.dll
PDO API
SQLSRV Native API
SQLSRV Native API
Core Functional Layer
SQL Server Native Client (ODBC)

SQL Server Driver for PHP Tips
Scrollable Cursor: scrollable but slower
Use sqlsrv_has_rows() w/ CURSOR_FORWARD if you only need to check if there’s data in the resultset, it’s faster and doesn’t move the cursor
If scrollable required, consider CURSOR_STATIC first
WarningsReturnAsErrors: ON by default
Remember to turn it OFF in deployment
Should we change default to OFF?
UTF-8 encoding
The default for PDO, available per col/param
Should we make this the default for sqlsrv_xxx?
Use transactions for DDL to improve performance

SQL Server Query Tips
Range query:
SELECT * FROM table ORDER BY date LIMIT 20,10
Use TOP & ROW_NUMBER
SELECT sub2.*,ROW_NUMBER() OVER(ORDER BY sub2._l2) AS _lFROM ( SELECT 1 AS _l2, sub1.* FROM ( SELECT TOP(30) * FROM table ORDER BY date ) AS sub1) as sub2WHERE _l BETWEEN 20 AND 30;
SELECT * FROM (
SELECT *, ROW_NUMBER() OVER(ORDER BY date)
AS _l FROM table
) AS t
WHERE _l BETWEEN 20 AND 30
ORDER BY _l;

Web Platform Installer
Easy way to install IIS components, PHP 5.2, PHP and Asp.Net web applications etc.
Demo
PHP 5.3 will be offered through WebPI soon

Community participation
WinCache is on PECL and SQL driver for PHP is on codeplex
IIS and WinCache documentation on php.net
Participating on PHP newsgroups
Working with PHP developers to improve PHP and PHP installer
Working with PHP application developers to integrate URLRewrite, WinCache

Miscellaneous tips
Set IP address of MySql machine in hosts file
Build PHP yourself and statically link WinCache
Compile and optimize using PGO for maximum performance
URLRewrite
Includes htaccess importer
Use IIS warm-up module to fill opcode cache before first request arrives

What is Windows Azure?
It’s an Operating System
In the Cloud.
Simple Answer?
Windows Azure: operating system as an online serviceMicrosoft SQL Azure: fully relational cloud database solutionWindows Azure platform AppFabric: connects cloud services and on-premises applicationsMicrosoft Codename “Dallas”: information marketplace for data and web services

What about hosting my PHP + MySQL on Windows Azure?
Yes, you can do it
If you do, you are using Windows Azure only as an infrastructure service
This means you are responsible for managing the infrastructure
