php 5.2.1, apache 2.2.14, gd, prefork, worker support

[csgonan]

My apache process is using alot of memory and it was compiled with prefork.  It was suggested to switch to worker and fast-cgi.  This is the configure command. 

 

1)  Some posts indicated gd was not compatible with threads.  Is that correct?  Are any of these items not compatible with threads?

 

Configure Command =>  './configure' '--with-apxs2=/usr/local/apache2/bin/apxs' '

--with-mysql=/usr/local/mysql' '--with-pear' '--with-libxml-dir=/usr' '--with-my

sqli=/usr/local/mysql/bin/mysql_config' '--enable-mbstring' '--with-curl=/usr/lo

cal/curl-7.19.5' '--with-gd' '--with-jpeg' '--with-jpeg-dir=/usr/lib'

 

2)  Do the current php scripts have to be modified to utilize fast-cgi? 

 

Thank you in advnce for any help.
