Hi, I'm using a Sony VAIO W series netbook dual booting Lucid and Win 7 Pro. I use Firefox and Chrome on both installations. Browser response is near instantaneous on Win 7 but mush slower on Ubuntu. It's not a problem with connection speed. It seems that on Ubuntu the browsers spend most of their time doing DNS lookups, while on Win 7, rrecent DNS responses are cached. Does anyone know what's going on? Thanks, Dick Dowdell
