Moving to Apache

I installed Mediawiki on an internal IIS server, but the original page loads can easily be 10-15 seconds.

LocalSettings:

$wgCacheDirectory = "$IP\cache";

$wgFileCacheDirectory = "$IP\cache ";

$wgEnableSidebarCache = true;

$wgUseFileCache = true;

$wgShowIPinHeader = false;

$wgEnableParserCache = true;

$wgCachePages = true;

$wgMainCacheType = CACHE_ACCEL;

$wgMessageCacheType = CACHE_ACCEL;

$wgParserCacheType = CACHE_ACCEL;

$wgMemCachedServers = array();

$wgShowExceptionDetails = true;

$wgShowDBErrorBacktrace = true;

$wgDebugComments = true;

$wgDebugLogFile = 'C:\Windows\Temp\MediaWiki\debug-{$wgDBname}.log';

wfLoadExtension( 'WikiEditor' );

wfLoadExtension( 'PluggableAuth' );

wfLoadExtension( 'Auth_remoteuser' );

wfLoadExtension( 'LDAPAuthentication2' );

wfLoadExtension( 'LDAPAuthorization' );

wfLoadExtension( 'LDAPProvider' );

wfLoadExtension( 'LDAPUserInfo' );

wfLoadExtension( 'LDAPGroups' );

php.ini:

[PHP]

display_errors = On

log_errors = On

error_log = C:\Windows\Temp\MediaWiki\php.log

[WinCache]

extension = php_wincache.dll

wincache.fcenabled = 1

wincache.ucenabled = 1

wincache.fcachesize = 64

wincache.fcndetect = 1

wincache.maxfilesize = 256

wincache.chkinterval = 10

wincache.enablecli = 1

wincache.ucachesize = 8

wincache.scachesize = 8

[opcache]

zend_extension=php_opcache.dll

opcache.enable=1

Once the page is loaded first time, it can take less than a second to reload, but 'new' pages still take anywhere between 6-20 seconds to load.

Any ideas as to how I can improve this or what to look for?

Windows Server 2016

IIS 10.0

PHP 7.3

WinCache 2.0.0.8 7.3

so beyond caching, the next step would be to look at a profile of a page taking a long time to load. See Profiling for help on how to generate one. Post the profile here or in a pastebin. You could also try increasing wincache.ucachesize to 16 which might help or might do nothing.

Note: the majority of performance testing is done on apache+mysql+linux. Performance may be better on that platform (of course switching is not an option for most people)

For the second time I have left it over night and come back to 500 Internal Error in the morning. I have every kind of logging on but there are no errors. I think I am going to need to move it to Linux.
