How can I check if too many / poorly written mod_rewrite rules are using up a lot of CPU?
httpd processes are using a lot of CPU on my server. I have about 70 mode_rewrite rules without special RewriteCond directives and id evyerthing fails, I have this:

    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^([a-zA-Z0-9\-]+)(\/(.*))?$ index.php?module=appindex&list_identifier=$1&raw_query=$3 [L,QSA]

I have about 100.000 hits / day. 

Is there anyway I can log the CPU usage caused by mod_rewrite?

Thank you.
