Mine are: 

rikjoh at sparhawk:~> cat /etc/hosts

127.0.0.1       localhost
192.168.1.2     talen.rikjoh.com www.rikjoh.com ftp.rikjoh.com  talen
192.168.1.3     sparhawk.rikjoh.com     sparhawk
192.168.1.6     cups.rikjoh.com         cups
192.168.1.253   alpha.rikjoh.com        alpha
192.168.1.254   wall.rikjoh.com         wall

rikjoh at sparhawk:~> cat /etc/resolv.conf

domain rikjoh.com
nameserver 65.173.196.10
nameserver 194.218.252.4

And thats plenty for my static IP system at home

The problem is if you still use the same resolv.conf and hosts at school as 
you do at home. Lets say the school network doesn't find the relevant DNS 
servers, it may slow things down. Also if the name given by the school DHCP 
conflicts with your resolv.conf it might slow things down.

I would check the DHCP settings.
Especially
DHCLIENT_SET_HOSTNAME
DHCLIENT_MODIFY_RESOLV_CONF
DHCLIENT_SET_DEFAULT_ROUTE

all in /etc/sysconfig/network/dhcp

also check /etc/sysconfig/network/ifcfg-* to make sure everyting looks ok.
