I get worried by blanket statements such as "leaving KeepAlive on will probably not be in your best interests." Using Keep-Alive is generally a good thing in terms of web performance. Not having to establish a new HTTP connection for each new asset request is gold. The problem is not with Keep-Alive per se, it's more about Apache's process model (assuming you're using mod_php) - the fact that you have a large (10-100 MB) process sitting there doing nothing. My advice would be to either use Apache with mod_fcgid (and php-fpm) or jump to nginx + php-fpm. We host a number of WordPress sites using Nginx and the stability has improved massively.
