I'm testing a new Server. This isnt really a peak time for my server (2pm), but still its running a bit slow, I was checking the ESTABLISHED connections using the following command:

# netstat -ntu | grep :80 | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -n

My MaxClients are set to 50. So as you can see on the picture, only 10 people are eating most of my ram. I got a server with 4GB Ram (2.7GB free for apache) but each apache process is eating 53MB each, wich mean im only allowed to accept 50 process.

The KeepAlive = Off, but I notice those connections arent closing fast enough, is that normal?
