PHP5 AS ISAPI
Memory Usage by Apache:
Mem Usage: 104MB
VM Size: 219Mb
and
Small usage by core httpd.exe
Mem Usage: 200k
VM Size: 10Mb
And question what is your Mem usage by apache now in PSexplorer a had 29 active connection. Why i ask meybe PHP5 As Fast cgi has smaller mem usage or other config can do better performance. My advice for height mem usage is restart apache per hour then all worker mem are free.
ps.
Ohh my terible engrish wrr |

I am running php as Fastcgi (mod_fcgid from our download page) at the Apache Lounge and the memory usage of httpd.exe is now after some time ~100M and two php processes of ~15M each. Mod_fcgid "kills" a php proces after predefined time and/or number of requests and starts a new one. When I runned php as module it was far over 400M and was growing and growing. Your milage may vary.
So running as Fastcgi memory usage of Apache is far less en the Speed is on par when running as module. There are advantages to running PHP with FCGI. Separating the PHP code from the web server removes 'bloat' from the main server, and improves the performance of non-PHP requests. Secondly, having one permanent PHP process as opposed to one per apache process means that shared resources like persistent MySQL connections are used more efficiently. And maybe even more important is stability, since I run FCGI my server never crashed caused by php (extension) errors. |

This is nice thx for advices now ram usage is 500Mb sic
In test of old performance like on lighttpd ther are only show graph for ISApi Apache but not for fastcgi.
And what witchs PHP as Fast CGI:
- security [ server/php/php-cli.exe ]
- register globals whose 'on' in my old hosting in Fastcgi mode can i turn off in this mode
+ performance
+ stable

How do you configure apache to to use PHP with FCGI? I've been searching but can't find out what lines to add to my apache and/or php configuration. I've downloaded the new FCGI module from the downloads section here, but im unsure of how to setup php to use FCGI. Right now php is running as a module with apache, and crashes every few minutes and the memory usage goes over 400+ |
