need some help with mongrel and performance problems

I run a Debian/Etch witch Apache 2.2.3 and self installed Rails 1.2.3.

apache2 configuration:

<Proxy balancer://beta>
     BalancerMember http://192.168.178.200:8100
     BalancerMember http://192.168.178.200:8101
     BalancerMember http://192.168.178.200:8102
     BalancerMember http://192.168.178.200:8103
     BalancerMember http://192.168.178.200:8104
     BalancerMember http://192.168.178.200:8105
</Proxy>

<Virtualhost *:80>
        ServerName       www.gissmoh.de
        ServerAdmin      gissmoh-/upiLifMog2ELgA04lAiVw@public.gmane.org

        ProxyPass /images !
        ProxyPass /stylesheets !
        ProxyPass /javascripts !

        ProxyPass / balancer://beta/
        ProxyPassReverse / balancer://beta/

        SetEnv force-proxy-request-1.0 1
        SetEnv proxy-nokeepalive 1

        # RewriteEngine On
        # DirectoryIndex index.html

        ...

bash:

mongrel_rails start -d -p 8100  -e production
mongrel_rails start -d -p 8101  -e production
mongrel_rails start -d -p 8102  -e production
mongrel_rails start -d -p 8103  -e production
mongrel_rails start -d -p 8104  -e production
mongrel_rails start -d -p 8105  -e production


The website www.gissmoh.de is very, very slow :-(

The host is connected via a dyndns.org account and uses a Broadband 
ADSL connection (512Kbit upstream, 6Mbit downstream).

One year ago I run a PHP application on the same machine and it was 
a lot faster.

Didn''t I get mongrel and apache2 configured right??

Thanx

A quick firebug analysis shows that most of the time is used fetching 
CSS and JS files. One way of resolving this is by using multiple asset 
hosts, a starting point for this could be:

Re: need some help with mongrel and performance problems

About 100 reqs/sec is very good performance result. For 24h it would
be 8640000 request. Not bad...

But I think it''s too slow to run the rails app here.... I think I 
must look for a dedicated machine....
