Ok, I'll at this in shortly. |

You have misread the columns. |

23 |
Align the columns better or look at the web version "http://localhost/server-status" in a table capable browser. |

The ~50 you see is NOT the size, it's the time in seconds since the last |
28 |
request. The 'W' shows that the request is still open, so that IS a |
29 |
serious issue. I would turn off keepalives + persistant connections in |
30 |
apache/php totally. There is minimal performance gain with them in PHP |
31 |
anyway. The '12.94Mb' for the Child column is how much that Apache child |
32 |
process has transfered over its lifetime. |
33 |
9170 connections and 12.94Mb is quite low traffic. |
