Slow web address resolution is most likely a problem with your DNS servers. The DNS server addresses you normally get from your ISP dynamically (or router). My dad's ISP is weird because on his Suse, the DNS address that it gets dynamically makes his internet not work. I just went to Control Center, Yast Modules, Network Services, DNS and Hostname, and manually fixed the name server 1 and name server 2. You technically only need 1 name server (DNS server), but if that one goes down, so do you. If you have to update this every boot up, I'd suggest unchecking the Update via DHCP option. This will make your name server static, but keep in mind your DNS server (name server) should be different if you move your computer around (i.e. take it to school, take it to work, use at starbucks). DNS servers are meant to be fast and if you dont use the one given on the network you're using, it'll slow you down.
Hope this helps
