Looks like your ISP's DNS server is very slow. I would very seriously consider setting up a local caching DNS server, and possibly allow it to locally resolve if the ISP server is being slow (ie: "forward first" instead of "forward only"). Or, if you've got decent bandwidth, and a lot of hosts, just set up your own resolver and don't even bother forwarding to them.
