When I enabled KeepAlive on my server, response times of all my php pages (measured using browser tools) are now nearly equal to the timeout value specified in the KeepAlive settings. 

Foe example, the following settings:

```
KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 30

```

will lead to response times of 30 seconds for every page!

I know KeepAlive and response time should not be related, but I do not know how to explain this.
any clue?
