Revision [21012]
Edited on 2010-02-03 15:12:11 by AlexFranke [Replaces old-style internal links with new pipe-split links.]Additions:
For unregistered visitors the Wikka site is very slow while registered (logged-in) visitors don't have any problem. May also cause "Fatal error: Maximum execution time of 30 seconds exceeded in [path]\libs\Wakka.class.php on line 1848".

Additions:
~& You could uncomment the ##gethostbyaddr()## in ##""GetUserName""()## in ##wikka.php##. Everything will work but you will get the IP's of guest visitors instead of the hostnames, when they store a page, for example. This can also be a temporary solution if you're experiencing temporary troubles with the DNS servers. --- -- RobinW

=====Extreme slowness for unregistered users=====
===Symptoms===
For unregistered visitors the Wikka site is very slow while registered (logged-in) visitors don't have any problem.
===Cause===
By default, Wikka does a DNS name lookup for the node an unregistered user is connecting form. If the DNS lookup from the server is slow, this will result in very long response times. For logged-in users such a lookup doesn't take place, so they don't experience such slowness.
===Applies to===
All current Wikka versions.
===Solution===
//will follow//
~&I added an email field mandatory for anonymous user when they enter comments and got rid of the php function "gethostbyaddr" in wikka.php. Nevertheless, I didn't add it for new page creation.

//This page is a **template** intended for documentation of **workarounds** for unusual Wikka problems. This page belongs to CategoryTemplate (which contains more handy templates). To create a Wikka **workaround** page, [[http://wikka.jsnx.com/WorkaroundTemplate/clone clone this page]] (most workaround page names end in 'Workaround' so it's useful to stick to that convention) and replace the title with a problem description (in a few words). Then remove this paragraph and provide actual page content in the outline below.//
