[Mediawiki-l] PHP5 and Performance

[atticus at adventurevacationtrip.com]

Hi,

When I first installed mediawiki 1.11.0, I was prompted that I am not  
using php5 and have to install via a .php5 link. So I went ahead and  
added the following to .htaccess:

AddHandler application/x-httpd-php5 .php .php4 .php3 .phtml

It's working fine now but all the URLs contain .php5 in them (eg  
http://example.com/index.php5?title=Help:Contents). How can I have  
nice URLs like mediawiki's (eg  
http://www.mediawiki.org/wiki/Help:Contents).

I also cannot help feeling that these .php5 pointings are making my  
wiki slow. When I ping both my wordpress blog and wiki. Wiki almost  
always take double the time.

I was wondering why I had the problem with .php5 in the first place.  
My host is using PHP version 5.2.5 and if it helps, Server API is CGI.  
Is it possible for me to for my wiki to use normal .php instead of  
.php5?

Any advice?

Regards,
Atticus
