Just FYI, with the reddit pounding the server is staggering under the load. I noticed that the server had keep alives enabled with limits of 15 seconds and 100 requests. While this is a benefit when the site isn't under high load, it means an apache process is tied up for 15 seconds on each connection. I went ahead and just shut KeepAlive off in /etc/apache2.conf. This has made the site quite a bit more responsive.
