So after posting to the Gentoo forums, I received a link to this discussion - http://kerneltrap.org/node/6723 Basically it is a kernel issue and has something to do with scaling and windows sizes and that there is probably a bad box between my connection and the target websites. I'm not sure what the final resolution will be, but there is a workaround by disabling windows scaling. setting /proc/sys/net/ipv4/tcp_window_scaling===0 No sure what the consequences of disabling scaling are either, but this is just something to keep in mind when using a 2.6.17 kernel. Thanks for all the help and suggestions on the list.
