    Questions / Open Discussion
  • 3. 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
  • 4. 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
  • 5. 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% +)”
  • 6. 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!
  • 7. Why use opcode cache?
    To serve index.php in WordPress, PHP has to read, parse, compileand execute more than 100 php files!
  • 8. 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
  • 9. 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
  • 10. 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)
  • 11. 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
  • 12. 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;
  • 13. 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
  • 14. 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
  • 15. 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
  • 16. What is Windows Azure?
    It’s an Operating System
