Coming from the discussion on Github, I comment on your Trac here to help you with the deployment.

Documentation for Windows:

We adjusted it with the Tools and Cache plugins that might help, especially WinCachePHP. The project is on Sourceforge ( We used the binaries of Wincache 1.3.7 which are packed in a MSI file, that we unpacked.

File Download depends on PHP Version, Thread-Safe and VC environment, but you want to compile it, IIRC.

PHP.INI Params (I missed some in the MB issues discussion):

  • max_execution_time = 150 (should help for starting first time)
  • extension = php_wincache
  • session.save_handler = wincache
  • zend_extension=C:/bin/php/5630/ext/php_opcache.dll
  • opcache.enable=1
  • opcache.memory_consumption=64
  • opcache.interned_strings_buffer=4
  • opcache.max_accelerated_files=2000
  • opcache.max_wasted_percentage=5

thank you so much for filing these instructions here; very helpful, I will follow your advice on the php.ini changes. Will dive in :)

I did all the changes before - except the max_execution_time = 150. Its still the same slow. The path to the zend_enxtension in my case is C:/ms4w/Apache/php/ext/php_opcache.dll. Is that wrong? Do I need to install php aside from ms4w ?

I checked the installation with MS4W again on a Windows machine.

Wincache is not available for TS (thread-safe) Version of PHP, so I only enabled Opcache.

Second are the parameters of the FCGID configuration in httpd.conf. Fastest results are with this parameters (as described in:

FcgidInitialEnv PHPRC "c:/PathToPhp.Ini.Directory"
AddHandler fcgid-script .php
FcgidWrapper "yourpath/php-cgi.exe" .php

The important change is the AddHandler instead of SetHandler. I commented out the part:

<Location "/fcgi-bin">

I uploaded the changed httpd.conf (for diff) at:

@axel thanks for all the tips. It is working well, very fast! I enabled OPcache, as well as PHP as FastCGI, in today's MS4W 3.2.2 release, and I have packaged Mapbender inside the setup.exe installer.

(note that much of the Apache config for Mapbender lives in C:\ms4w\httpd.d\httpd_mapbender.conf)
