fastcgi too slow in debian squeeze

["J. Bakshi" <bakshi12@gmail.com>]

Dear list,

I have been suffering with the slow performance of my apache server (2.2.16) running
on debian wheezy. I have finally pointed out it is the fastcgi which makes the web server
so slow. But I really need it as I am also hosting some sites which do require php 5.2

The symptoms of having the fastcgi is very annoying.

-1 All sites need 30 or so sec. to open and after that the browsing is again normal for that site.
-2 Sites having fastcgi enabled is frequently facing "Internal Server Error" and through log I can see


`````````````````

The usr/lib/cgi-bin/php52/php52.fcgi is

```````````````````````
#!/bin/sh

I have also modified  /etc/apache2/mods-enabled/fastcgi.conf as

````````````````
<IfModule mod_fastcgi.c>
  AddHandler fastcgi-script .fcgi
  #FastCgiWrapper /usr/lib/apache2/suexec
  FastCgiIpcDir /var/lib/apache2/fastcgi

### modification######
FastCgiConfig \
-idle-timeout 60 \
-singleThreshold 50 \
-maxClassProcesses 50
### end mod ##########

</IfModule>

Could any one please suggest how can I get rid off #1 and #2 ?

Thanks
