I have a server setup with FreeBSD 8.2-STABLE running Apache/2.2.22.
Since this morning it became very slow. Connections are quickly established, but the response is very slow. This is valid even for regular files (not scripts) such as images, css and so on. I can't figure out, what could have happened since yesterday. I didn't change any configuration. The usage of
top to make some profiling don't show anything unnormal - everything looks good. The system idles almost 100% of the time and the number of incoming connections is not so high.
What can I do to determine the reason for the slowing down?
