very bad fcgi performance

[nils]

On my old server, the cms(drupal6) was very fast, <10ms/request, on the new server with ispcp the same request takes several seconds
Both with the opcode/usercache system apc installed...
Ispcp's user interface is sometimes slow,too, but not everytimes, so i'm not sure..

I use mpm_prefork_module (static) with default tuning-conf:

Code:

<IfModule prefork.c>
    # number of server processes to start
    # http://httpd.apache.org/docs/2.2/mod/mpm_common.html#startservers
    StartServers       1
    # minimum number of server processes which are kept spare
    # http://httpd.apache.org/docs/2.2/mod/prefork.html#minspareservers
    MinSpareServers    1
    # maximum number of server processes which are kept spare
    # http://httpd.apache.org/docs/2.2/mod/prefork.html#maxspareservers
    MaxSpareServers    5
    # highest possible MaxClients setting for the lifetime of the Apache process.
    # http://httpd.apache.org/docs/2.2/mod/mpm_common.html#serverlimit
    ServerLimit       10
    # maximum number of server processes allowed to start
    # http://httpd.apache.org/docs/2.2/mod/mpm_common.html#maxclients
    MaxClients        10
    # maximum number of requests a server process serves
    # http://httpd.apache.org/docs/2.2/mod/mpm_common.html#maxrequestsperchild
    MaxRequestsPerChild  10000
