Re: [SLE] Linux still surfs slower than Windows

Does it take long to resolve the address to ip or is the
page loading slow?

Maybe you can try connecting to sites with their ip address
and see if it loads same speed as w2k than using www. If it
does then there must be something not right with dns?
